Well, in answer to your question, I found it to be a handy feature too,
and wanted to get a whole program listed in this form.  What I did was
to write a REXX exec that reads in the C program and merges it with the
ASM file.  I meant to get around to re-writing the exec in C, but
haven't so far.  You should be able to do it pretty simply, though.

Have a look at the output of the following:
       tcc -S prog.c       (namely prog.asm)
Notice the lines labeled
;	debug L ##         (## is the corresponding line in the C prog)
So now make a C prog that reads in a C source code into an array
(because you may need to reference them more than once) and then read
the .ASM file.  When you see a line with the above prefix, spit out the
C line with the right number. Lines without the right prefix, just spit
out.

You could avoid the array by doing a simple merge kind-of-thing.  For
the few cases when you would need a line from the source more than once,
you could vote to simply put out the ?debug line.

Good luck.
