Is there some reason gcc hasn't been or can't be enhanced to provide output for a cross-referencing

No reason why it can't be, and the reason it hasn't is that
no one has done it. Actually strictly you don't mean gcc
here, you are referring to particular front ends, since
the notion of referencing is somewhat language dependent.
So probably you are thinking of C and/or C++. Note that
GNAT, the Ada front end, does indeed output full
information for xref purposes, in the form of ali
files (it would indeed be nice if the C++ compiler
would generate something similar!)
