Well, gdb can be taught (perhaps) about the source code through #line
directives in the generated source.
To solve the problem of printing lisp variables like bell-volume, when
C only understands bell_volume, we would have to teach gdb how to turn
lisp variable names into C variable names, but that strains the
capabilities of gdb's command language.
Anyways, yes, the resulting program will be much harder to debug. And
this preprocessor is supposed to make the developer's life easier.
