Do not redefine WINVER

Compiling different parts of the sources with different WINVER may lead to
subtle and hard to detect problems. Better use the same value everywhere.
The existing error message suggests that this was wanted anyway, and it
fixes a compiler warning when cross-compiling for mingw on linux. Our code
does not require a specific value, only a minimum value of 0x5000, which
means the resulting executable will require at least Windows 2000.
