That would be better alright.

Also, I see calls to error() when there are no macros.
I think this shouldn't be an error.
For example, if it were done in a script it shouldn't break the script
if no macro info was found.
An informational message would be better IMO.
"info var foo" doesn't print an error on stripped binaries, for example.

E.g. here:

  if (! ms || ! ms->file || ! ms->file->table)
    error (_("GDB has no preprocessor macro information for that code."));
