Well. If only it would not haven been named libstdthreads. I mean, it's
a C standard interface. Quite confusing not to adhere to the
conventional naming scheme. It's not -lstdc -lstdm but -lc -lm.
-lstdc -lstdm -lstdthreads
vs.
-lc -lm -lthreads
I'am not sure, it is a good idea to not call it libthreads, instead of
libstdthreads. There will be reasons I don't know about. For consistency
it really should be called libthreads instead of libstdthreads.
So long and now to something completely different,
