If you cheat: all of them. GCC supports in-line assembly.
Of course, that’s not an interesting observation.
It gets (somewhat) interesting when you realize that one may inadvertently include in-line assembly. Do you call including system headers that happen to contain inline assembly cheating? Including headers for a standard C library? Compiling with old-fashioned compiler flags (for example to generate FPU instructions for the x87)?
