On Windows the filesystem is not case sensitive and this will link just fine.
However, the Windows SDK provides the import library with the lowercase name.
Adjust the name so that the link actually succeeds on case-sensitive file
systems (like on Linux). This fixes the Windows cross-compile.
The system header depends on Windows.h but does not include it itself. This
results in base Windows types (e.g. ULONG) to be undefined. Include the header
to include the needed typedefs.
