Building R package with .c sub-routine files

Lets say I have two source files  file1.c and file2.c

The latter just contains sub-routines to be used by the first. i.e. in file1.c I
have the line

#include "file2.c"
That's not the normal way to program in C:  normally you'd have a 
separate file2.h header file which is all you'd include in file1.c, and 
compile file2.c using the same header file to a separate object file.

I guess you could probably get your scheme to work by renaming file2.c 
to file2.h, but putting actual executable code into a .h file seems 
pretty strange.

Let's say "R CMD SHLIB file1.c" runs perfectly and I want to include the code in
a package, "R CMD build" also runs fine but R CMD check" gives

* checking whether package 'myPackage' can be installed ... ERROR
Installation failed.
See '/pathto/myPackage.Rcheck/00install.out' for details.

basically the compiler is trying to compile file2.c independantly of file1.c
which is not what I want and prevents a proper build

What's the easiest way to enforce the correct file dependencies when building  R
packages?
