The former shows up as "foo x", the latter as "foo() x".

Yes, the example could be enhanced to illustrate that. And a little
more about the ``transformation'' from what is found in the *.c file
to the stabs entry.

But, as to the latter -- am I misunderstanding you? Are you asking
for text about when something is replaced versus when it isn't
replaced? If yes, that is *WAY* beyond the scope of the file. The
file deals exclusively with *STABS*. When something is replaced vs
not replaced is a CPP issue. It has nothing to do with STABS.
