This was Solaris 8 (sparc), though I doubt that matters. Here's the
behavior I observed:
depbase=`echo argp-fmtstream.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
gcc -m64 -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -g -O2 -MT
argp-fmtstream.o -MD -MP -MF $depbase.Tpo -c -o argp-fmtstream.o
argp-fmtstream.c &&\
mv -f $depbase.Tpo $depbase.Po
In file included from argp-fmtstream.c:32:
argp-fmtstream.h:206: warning: C99 inline functions are not supported;
using GNU89
argp-fmtstream.h:206: warning: to disable this warning use
-fgnu89-inline or the gnu_inline function attribute
argp-fmtstream.h:219: warning: C99 inline functions are not supported;
using GNU89
... and lots more warnings like that.
I installed the following workaround into gnulib for now. I suspect
we might need a better solution in the long run, but this solves the
immediate problem.
