Rainer,
This patch re-broke pr47917.c on HP-UX because it doesn't see the
snprintf prototype in stdio.h when using -std=c99. I do see it if I use
-std=gnu99 instead and that is what I probably should have used in the
first place. I was wondering if using -std=gnu99 would also work for
mips-sgi-irix6.5 in place of "-std=c99 -D_XOPEN_SOURCE=500".
If so I would propose this patch to just use -std=gnu99 for all
platforms:
$ svn diff gcc.dg/torture/pr47917.c
