I'm running a test build using this approach.

I think at some point after 2.5 releases I will look at updating
my now-very-ancient w32 build setup to something slightly less
terrible (in particular, moving to mingw-w64; I'm pretty sure the
mingw32 toolchain I have now produces binaries that wouldn't run
due to TLS bugs if we tried them, and at some point it would be
neat to see if 'make check' can be made to work via WINE.) But I'd
rather not do that mid-release process.
