This is avaliable for UNIX too.
Unix uses COFF (Common Object File Format) and all compilers on a UNIX
machine *should* use this format for thier object code.
The linker ld can then bind all the different objects together.
We did so with C, Pascal, Fortran and Assembler.
The MOCKA Compiler has the DEFINITION Module interface mentioned above.
It's called FOREIGN MODULE there and works very well.
