[x264-devel] x264 on x64

[Steven Walters]

No, x264 in it's current state does not support visual studio's
compiler as it does not support the C99 convention that x264 utilizes.
Direct264 is the next closest thing for the time being, as it removes
the C99 requirements of x264 so it can be compiled with MSVC.

I do however have a patch that adds support for Intel's compiler
(which does support C99), which then allows building of fully MSVC
compatible libraries.

This is has been in the works for a while but I lately halted it due
to an issue with pthread-win32 crashing in the 64bit version of x264.
This is on the back burner until i get another patch to alleviate the
pthread-win32 issue finalized and committed.
