There's a ton of header files that can be included in assembly code and which also contain C declarations and definitions. This is achieved by adding a:
#ifndef __ASSEMBLY__ #endif
Blocks around the C code. Especially for smallish or single-purpose files this is often a cleaner method than splitting the file.
There's more than 40 such headers on x86 alone.
