Interesting... MESS compiles flawlessly as well, but I get this linker error at the end:

Linking mess.exe...
obj/windows/mess/mess/drivlist.o:drivlist.c:(.rdata+0x1928): undefined reference to `driver_victor9k'
collect2: ld returned 1 exit status
make: *** [mess.exe] Error 1

I don't get this on Linux, haven't tried Win 7 x64 yet... but whatever it is, I doubt it's related to the new tools.

This was tested with SVN r17537.
