-#-----------------------------------------------------------------------------
-# GNU makefile definitions for building WCSLIB 4.17
-#
-# makedefs is generated from makedefs.in by configure. It contains variable
-# definitions and some general-purpose rules for building WCSLIB.
-#
-# Targets defined here
-# --------------------
-# printenv: Print the environment as seen within makefile rules.
-# show: Print the values of all makefile variables used.
-#
-# Notes:
-# 1) If you need to make changes then it may be preferable to modify
-# makedefs.in (not makedefs). The makefile will detect this and
-# automatically re-run config.status to regenerate makedefs.
-#
-# 2) There are three choices for trigd functions - cosd(), sind(), tand(),
-# acosd(), asind(), atand(), and atan2d(), made by setting WCSTRIG:
-#
-# 1: Use the wrapper functions supplied with WCSLIB (default):
-# WCSTRIG := WRAPPER
-#
-# 2: Use native trigd functions supplied in a mathematics library such
-# as libsunmath (you will also need to add the library to the LIBS
-# variable below):
-# WCSTRIG := NATIVE
-#
-# 3: Use C preprocessor macro implementations of the trigd functions
-# (this method is typically 20% faster but may lead to rounding
-# errors near the poles):
-# WCSTRIG := MACRO
-#
-# 3) Variables for creating the shared (dynamic) library are currently
-# only set by 'configure' if the GNU C compiler is used. However,
-# you can set these variables by hand, preferably in makedefs.in.
-#
-# Shared libraries require position-independent code (PIC) which imposes
-# a performance overhead. Consequently the static libraries are
-# compiled separately without this option.
-#
-# The shared library will be installed with version number, e.g. as
-# libwcs.so.4.17 or libwcs.4.17.dylib with or without the symlink
-# required to make it visible to the linker (controlled by the SHRLN
-# variable). On Macs it is deliberately not created because its very
-# existence precludes static linking with the cctools linker. You can
-# still link dynamically by using -lwcs.4.17.
-#
-# 4) PGPLOT is Tim Pearson's Fortran graphics library with separate C
-# interface available from astro.caltech.edu. It is only required by
-# one utility, wcsgrid, and the test programs that plot test grids
-# (tprj2, tcel1, tcel2, tspc, ttab2, ttab3, twcsmix, and tpih2). You can
-# skip these by setting PGPLOTLIB to blank.
-#
-# It is difficult for configure to deduce what auxiliary graphics
-# libraries may be needed for PGPLOT since it depends on which of many
-# possible graphics drivers were selected when PGPLOT was installed.
-# Therefore it is quite likely that you will need to add additional
-# libraries to PGPLOTLIB.
-#
-# 5) CFITSIO is Bill Pence's FITS I/O library written in C with Fortran
-# wrappers, available from http://heasarc.gsfc.nasa.gov/fitsio.
-#
-# CFITSIO is required by three utilities, HPXcvt, wcsgrid, and wcsware,
-# and also by the test programs twcstab and twcshdr. wcsware and the
-# test programs use fits_read_wcstab() which is implemented by
-# getwcstab.c. However, this implementation is included in CFITSIO post
-# 3.004beta, so getwcstab.c is required here only for older releases
-# (controlled by variable GETWCSTAB). getwcstab.o itself is not inserted
-# into the WCSLIB object library.
-#
-# If available, CFITSIO is also optionally used for test programs
-# tfitshdr, tbth1, tpih1 and tpih2 by setting preprocessor macro
-# -DDO_CFITSIO.

+ - New function prjbchk() performs bounds checking on native spherical
+ coordinates. It is invoked automatically by the deprojection (x2s)
+ routines if prjprm::bounds&4 is set. Documented the new bounds
+ checking implemented by prjbchk() in the prologue entry for
+ wcsbchk(). Improvements to tprj1 to test the vector API of prjx2s()
+ and to deal better with out-of-bounds native coordinates returned by
+ it.
+
+ - Bug fixes in the projection routines: in hpxx2s() relating to bounds
+ checking, bug introduced at 4.20, reported by Michael Droettboom; in
+ parx2s() and molx2s() relating to setting the stat vector; in
+ hpxx2s() relating to implementation of the vector API; and in
+ xphx2s() relating to setting an out-of-bounds value of phi.
+
+* Fortran wrappers
+
+ - Wrapper for prjbchk(). Modified tprj1.f to track changes to the C
+ version.

-#-----------------------------------------------------------------------------
-# GNU makefile definitions for building WCSLIB 4.17
-#
-# makedefs is generated from makedefs.in by configure. It contains variable
-# definitions and some general-purpose rules for building WCSLIB.
-#
-# Targets defined here
-# --------------------
-# printenv: Print the environment as seen within makefile rules.
-# show: Print the values of all makefile variables used.
-#
-# Notes:
-# 1) If you need to make changes then it may be preferable to modify
-# makedefs.in (not makedefs). The makefile will detect this and
-# automatically re-run config.status to regenerate makedefs.
-#
-# 2) There are three choices for trigd functions - cosd(), sind(), tand(),
-# acosd(), asind(), atand(), and atan2d(), made by setting WCSTRIG:
-#
-# 1: Use the wrapper functions supplied with WCSLIB (default):
-# WCSTRIG := WRAPPER
-#
-# 2: Use native trigd functions supplied in a mathematics library such
-# as libsunmath (you will also need to add the library to the LIBS
-# variable below):
-# WCSTRIG := NATIVE
-#
-# 3: Use C preprocessor macro implementations of the trigd functions
-# (this method is typically 20% faster but may lead to rounding
-# errors near the poles):
-# WCSTRIG := MACRO
-#
-# 3) Variables for creating the shared (dynamic) library are currently
-# only set by 'configure' if the GNU C compiler is used. However,
-# you can set these variables by hand, preferably in makedefs.in.
-#
-# Shared libraries require position-independent code (PIC) which imposes
-# a performance overhead. Consequently the static libraries are
-# compiled separately without this option.
-#
-# The shared library will be installed with version number, e.g. as
-# libwcs.so.4.17 or libwcs.4.17.dylib with or without the symlink
-# required to make it visible to the linker (controlled by the SHRLN
-# variable). On Macs it is deliberately not created because its very
-# existence precludes static linking with the cctools linker. You can
-# still link dynamically by using -lwcs.4.17.
-#
-# 4) PGPLOT is Tim Pearson's Fortran graphics library with separate C
-# interface available from astro.caltech.edu. It is only required by
-# one utility, wcsgrid, and the test programs that plot test grids
-# (tprj2, tcel1, tcel2, tspc, ttab2, ttab3, twcsmix, and tpih2). You can
-# skip these by setting PGPLOTLIB to blank.
-#
-# It is difficult for configure to deduce what auxiliary graphics
-# libraries may be needed for PGPLOT since it depends on which of many
-# possible graphics drivers were selected when PGPLOT was installed.
-# Therefore it is quite likely that you will need to add additional
-# libraries to PGPLOTLIB.
-#
-# 5) CFITSIO is Bill Pence's FITS I/O library written in C with Fortran
-# wrappers, available from http://heasarc.gsfc.nasa.gov/fitsio.
-#
-# CFITSIO is required by three utilities, HPXcvt, wcsgrid, and wcsware,
-# and also by the test programs twcstab and twcshdr. wcsware and the
-# test programs use fits_read_wcstab() which is implemented by
-# getwcstab.c. However, this implementation is included in CFITSIO post
-# 3.004beta, so getwcstab.c is required here only for older releases
-# (controlled by variable GETWCSTAB). getwcstab.o itself is not inserted
-# into the WCSLIB object library.
-#
-# If available, CFITSIO is also optionally used for test programs
-# tfitshdr, tbth1, tpih1 and tpih2 by setting preprocessor macro
-# -DDO_CFITSIO.

-# GNU makefile definitions for building WCSLIB 4.17
-#
-# makedefs is generated from makedefs.in by configure. It contains variable
-# definitions and some general-purpose rules for building WCSLIB.
-#
-# Targets defined here
-# --------------------
-# printenv: Print the environment as seen within makefile rules.
-# show: Print the values of all makefile variables used.
-#
-# Notes:
-# 1) If you need to make changes then it may be preferable to modify
-# makedefs.in (not makedefs). The makefile will detect this and
-# automatically re-run config.status to regenerate makedefs.
-#
-# 2) There are three choices for trigd functions - cosd(), sind(), tand(),
-# acosd(), asind(), atand(), and atan2d(), made by setting WCSTRIG:
-#
-# 1: Use the wrapper functions supplied with WCSLIB (default):
-# WCSTRIG := WRAPPER
-#
-# 2: Use native trigd functions supplied in a mathematics library such
-# as libsunmath (you will also need to add the library to the LIBS
-# variable below):
-# WCSTRIG := NATIVE
-#
-# 3: Use C preprocessor macro implementations of the trigd functions
-# (this method is typically 20% faster but may lead to rounding
-# errors near the poles):
-# WCSTRIG := MACRO
-#
-# 3) Variables for creating the shared (dynamic) library are currently
-# only set by 'configure' if the GNU C compiler is used. However,
-# you can set these variables by hand, preferably in makedefs.in.
-#
-# Shared libraries require position-independent code (PIC) which imposes
-# a performance overhead. Consequently the static libraries are
-# compiled separately without this option.
-#
-# The shared library will be installed with version number, e.g. as
-# libwcs.so.4.17 or libwcs.4.17.dylib with or without the symlink
-# required to make it visible to the linker (controlled by the SHRLN
-# variable). On Macs it is deliberately not created because its very
-# existence precludes static linking with the cctools linker. You can
-# still link dynamically by using -lwcs.4.17.
-#
-# 4) PGPLOT is Tim Pearson's Fortran graphics library with separate C
-# interface available from astro.caltech.edu. It is only required by
-# one utility, wcsgrid, and the test programs that plot test grids
-# (tprj2, tcel1, tcel2, tspc, ttab2, ttab3, twcsmix, and tpih2). You can
-# skip these by setting PGPLOTLIB to blank.
-#
-# It is difficult for configure to deduce what auxiliary graphics
-# libraries may be needed for PGPLOT since it depends on which of many
-# possible graphics drivers were selected when PGPLOT was installed.
-# Therefore it is quite likely that you will need to add additional
-# libraries to PGPLOTLIB.
-#
-# 5) CFITSIO is Bill Pence's FITS I/O library written in C with Fortran
-# wrappers, available from http://heasarc.gsfc.nasa.gov/fitsio.
-#
-# CFITSIO is required by three utilities, HPXcvt, wcsgrid, and wcsware,
-# and also by the test programs twcstab and twcshdr. wcsware and the
-# test programs use fits_read_wcstab() which is implemented by
-# getwcstab.c. However, this implementation is included in CFITSIO post
-# 3.004beta, so getwcstab.c is required here only for older releases
-# (controlled by variable GETWCSTAB). getwcstab.o itself is not inserted
-# into the WCSLIB object library.
-#
-# If available, CFITSIO is also optionally used for test programs
-# tfitshdr, tbth1, tpih1 and tpih2 by setting preprocessor macro
-# -DDO_CFITSIO.
