How about I just put define POSIX_C_SOURCE 200809L everywhere in the
header, that should do the trick, right? If I put it as a flag, it might
not be clear to someone who just yanks a test collection/source file out
of the suite. *shrugs*

Can you remind me what this does exactly? I can't remember anymore,
seemed to me it really was not needed. man says so as to not prevent the
signal handler from (paraphrasing:) calling a signal itself. I don't
need this, but you probably suggested it for some other reason then.
Please do remind me. Thanks.

These result from the -02 parameter. -Wall and -Wextra should report
nothing. I checked buf.c for clobbering, and corrected what was
necessary. There might be some other files where the same is needed,
will look into then.

Oh. That might be why I haven't heard of it. Well, I am using the other
one for sreturnf...
Thanks
