MS VisualC++ does not define _msc_ver, rather defines _MSC_VER. Too
see what GCC predefines, you can do the following on Unix:

  $ gcc -c -E -dM - < /dev/null

On DOS, you can create an empty file, say foo.c, and do this:

  $ gcc -c -E -dM foo.c

The ones that are always defined is __GNUC__, which specifies the
major version number and __GNUC_MINOR__, the minor version number.
For Mingw, it also defines __MINGW32__; if you're using MSVCRT
runtime, it also defines __MSVCRT__.

Please look at the documentation supplied with the compiler (or at least
made available from my site in variety of formats).
