Correct, due to lack of the first one I didn't notice :-)
It may be a good idea to have a general stdinclude.h or similar
which does the shielded includes.

Right, usleep is in the normal libc on Solaris and does not require
linkage to librt.

You mean timegm?

gnulib is not a lib to depend on. It is a configure-time inclusion
from upstream gnulib git which is then statically includes the
substitute functions.

Cool :-) BTW, is it correct that 1.0.0 has this in configure.ac?

I could if the setenv-issue would have been taken care of
which I didn't fix for the moment. I'll check this after
the 1.0.1 build, ok?
