[Debburn-devel] [PATCH] Fix union wait configure check for Cygwin

[Christian Franke]

Hi,

cdrkit-1.11.1 compilation on Cygwin fails in 
librols/spawn.c:wait_chld(). The code in include/waitdefs.h assumes that 
an existing 'union wait' implies that the WEXITSTATUS, ... macros accept 
a variable of this type as parameter. Cygwin's wait.h defines 'union 
wait', but uses POSIX 'wait(int *)' and 'WEXITSTATUS(int)'.

The attached patch enhances the configure check. Platforms with 
'wait(union wait *)' and 'WEXITSTATUS(union wait)' should still be 
supported (not actually tested).
