Apparently the mingw64 website does not provide a 64bit version of msys,
so configure will only build a 32bit version. You need to make sure the
minw64 compiler (e.g. x86_64-w64-mingw32-gcc.exe) is in the PATH, and pass
--host=x86_64-w64-mingw32 to ./configure

Just to make sure: do you really need a 64bit version of hwloc for use
in a 64bit application, or just hwloc tools which can run on a 64bit
windows? (in the latter case a 32bit build should be just fine)

Mmm, maybe you are using rc3? IIRC there was a mingw32 bug there
(that's why I didn't provide a windows build of it).

I've also tried mingw64 myself, and there's a problem with its
definition of LOGICAL_PROCESSOR_RELATIONSHIP which I've just
fixed in the svn, so please try tomorrow's nightly snapshot from instead.
