This replaces _MSC_VER macro with _WIN32 because the
former one is for MSVC and Visual Studio only and is
not defined in mingw environment. Wherease, _WIN32
macro is the proper way to check Windows platform
irrespective of compiler toolchain.

Not default nor even distributed in the .tar.gz, the cmake build allows for
loadable yasm plugins by building libyasm as a shared library.
Example plugins are in the plugins/ directory, and may be loaded into a
cmake-built yasm using the -N command line option (non-cmake builds will
not have this option).
Tested only on Linux so far, but should be relatively painless to port to
Windows thanks to the use of cmake rather than libtool to create shared
libraries.
The only modification to the main source tree is some conditional-compiled
additions to yasm.c.
