Just wondering, is the GNU C Library (glibc) usable on non-GNU and/or non-POSIX platforms such as Microsoft Windows?
Yes, its possible in theory, but not really worth it in practice. You would need to port the syscall interface, dynamic linker, and other parts to Windows or your platform of choice, and Glibc is not an ideal candidate for this.
If you really need a self contained C library, I would consider newlib or uClibc (or FreeBSD's/OpenBSD's libc) over glibc. Glibc is a complex beast, the alternatives are much smaller and easier to understand.
It is provided that glibc has been ported to the kernel in question. It may however be easier to use Gnulib instead as a wrapper around the native API.
