The cross-platform function is ctypes.util.find_library, which is currently not very useful on Windows. This patch changes it so that, on Windows, find_library("c") or find_library("m") finds the MS C runtime lib which exposes functions the are typically in libc and libm. The runtime lib in Windows is special anyway; the 'open' function, for example, is exported as '_open'. However, the easiest way on Linux (don't know about other platforms) to load the C runtime lib is to use ctypes.CDLL(None), which translates to dlopen(NULL) in C. Linux exposes all symbols from all loaded libraries to the returned handle.
