[Pkg-gauche-devel] Bug#777861: Bug#777861: Bug#777861: gauche-c-wrapper: ftbfs with GCC-5

[Jens Thiele]

reduced severity to important because i don't think the bug report is
valid.

see also:
http://sourceforge.net/p/gauche/mailman/message/33853322/

never got an answer to my last mail
looking at
http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-20150402-vivid.html
it seems only ppc64el and powerpc fail
likely this is caused by ubuntu using a "broken" gcc version (and not
caused by using gcc 5!)

you really should provide output of something like this:
$ cat << "EOF" > test.h
#define B() 1
#define A B
EOF
$ echo -e "100\nB()\nA"|gcc-YOURVERSION -E -include test.h -|tail


examples:

$ cat << "EOF" > test.h
#define B() 1
#define A B
EOF
$ echo -e "100\nB()\nA"|gcc-4.4 -E -include test.h -|tail
# 1 "<stdin>"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "./test.h" 1
# 1 "<command-line>" 2
# 1 "<stdin>"
100
1
B
$ echo -e "100\nB()\nA"|gcc-4.6 -E -include test.h -|tail
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "./test.h" 1
# 1 "<command-line>" 2
# 1 "<stdin>"
100

# 2 "./test.h"
          B
$ echo -e "100\nB()\nA"|gcc-4.7 -E -include test.h -|tail
# 1 "<stdin>"
# 1 "<command-line>"
