[Omake] Interfacing with C code

[Sashan Govender]

I have had to do something similar using OMake. I make a library of my
C object files and then use the variable OCAML_CLIBS in my Omakefile
that calls OCamlProgram.

e.g:
#In my library OMakefile
StaticCLibrary(my_lib, file1 file2)

#in my ocaml program makefile
OCAML_CLIBS=<path_to_lib>/my_lib

OCamlProgram(my_program, $(files))

This technique won't put the *.o files on the command line (like you
mentioned) but for my purposes it didn't matter that they were
amalgamated into a library.
