The git project pointed out a few things that "cygwin" (aka newlib) was
missing recently. I don't know if they were C99, POSIX, or just plain
glibc, but I've been thinking of adding some functionality just to
improve compatibility.

There are licensing issues with borrowing from glibc. That's one of the
reasons that newlib exists, IIRC.
