[FFmpeg-devel] Patch: Inline asm fixes for Intel compiler on Windows

[Reimar Döffinger]

This one will break Solaris for example.

This one should have told you that ICC doesn't have a problem with the
symbols but that MANGLE isn't working right.

> libavutil/x86/asm.h:#    define LOCAL_MANGLE(a) #a "(%%rip)"
> libavutil/x86/asm.h:#    define LOCAL_MANGLE(a) #a
> libavutil/x86/asm.h:#define MANGLE(a) EXTERN_PREFIX LOCAL_MANGLE(a)

As long as EXTERN_PREFIX is "_" as it should be on Windows, these two
lines above should produce _exactly_ the same string.
