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.
