Ok, thanks. Even linking with msvcp90 seems to be almost impossible
without hacks like EXTRALIBS = ../../dlls/msvcp90/msvcp90.dll.so,
so clearly it's not meant to be.

CompareObjectHandles probably wouldn't work, because the file handles
are actually distinct anyway (different modes and positions etc.).
