Concerning building under Windows, this uses a self-contained Makefile
in the msvc subdir. As long as the changes only affects configure.in,
it doesn't affect Windows build. However, this Makefile uses the same
variable names as substituted by configure, so if you change them, this
affects Windows build (ex: MACHINE -> MACHINE_VERSION)
