Can you fix this up using the same "mingw_fixups.h" trick?  That is,
something like:

static inline void myrename() { ...}

#define rename(...) myrename(...)

If you're having a conflict with a system header, you should be able
to include the header in mingw_fixups prior to the #define.

It's possible, but I'd prefer to keep the source code close to the
Linux version - it makes merges later on easier.
