The problem is that GNU as does not generate debugging information (such
as line numbers and symbol information) when generating object code. 
These
are directives like (this is for COFF):

        .def fn; .val fn; .scl 2; .type 044; .endef

for function fn.

The only way to do this is by inserting those directives by hand.  The
easiest way to do that is by having gcc compile a "typical" piece of C
with `-S -g' and look at the debugging directives generated by gcc.
This all depends very much on the debugging format used by the object
format (COFF, dwarf, etc.)
