As far as I understand the question (probably not really), a simple way to
do this is to (foreign-declare "#include \"foo.c\"") and add foo.h to the
source-dependencies of the file (see for example the simple-sha1 and
simple-md5 eggs, they do this).  No need for any special handling.

Of course it means your C files get a lot larger, and you don't benefit
from reduced compilation times from separate compilation.
