x264 is written in the C99 language.  It is rather silly to attempt to
compile it using a compiler that does not support that language!  As
such, we don't support MSVC, since it isn't a C99 compiler.
Fortunately, there are many other options.

Both ICC and GCC are cross-platform C99-supporting compilers which can
compile x264.
