The attached draft patches for setup and mingw64-headers (r4913) allow 
setup to be built cleanly and work correctly (AFAICS) with both i686 
toolchains.

The code also compiles cleanly on x86_64-w64-mingw32 but needs some 
additional LIBS as I circumvented autoload.c, which is clearly 32-bit 
specific and should be unnecessary on 64-bit Windows (being new enough 
to have all these functions).  This probably needs further functional 
changes and probably isn't useful until we have a 64-bit Cygwin, but it 
did expose some type incompatibilities.

These are NOT ready to commit right now; they are being posted to help 
collaboration with mingw-w64 to make this work.
