With the latest from gnulib, I get things like this expanded from
timespec.h, and they trigger many -Wmissing-declarations warnings
in coreutils:
#define _GL_TIMESPEC_INLINE _GL_INLINE
# 57 "timespec.h"
inline int
timespec_cmp (struct timespec a, struct timespec b)
{
return (a.tv_sec < b.tv_sec ? -1
: a.tv_sec > b.tv_sec ? 1
: (int) (a.tv_nsec - b.tv_nsec));
}
I have tentatively worked around it with the following,
but would be happy to avoid that commit altogether
if someone fixes the problem in gnulib "real soon":
