The real issue is that the convention -- .c versus .h -- recognize *two* 
kinds of files, but there really are *three* kinds of files:

- Files meant to be included that generate no code (.h)
- Files meant to be included that generate code (???)
- Files not meant to be included (.c)

Some projects -- including the Linux kernel -- have adopted the 
convention that the middle type should be .c, others .h, others probably 
other variants.  You typically want them treated as .h files for 
purposes of generating dependencies, but like .c files for purposes of, 
say, header file include guard checking.
