The asm syntax in FFmpeg is GNU syntax and part of "GNU C". If other
compilers (like ICC) support it, it's still "GNU C".

Surely they're conditional on ARCH_X86 or whatever it's called. If
this is set without checking for the ability to compile GNU C inline
asm, then that's a bug in configure.

There are no problems it will cause.
