So unrealistic that gcc even has a documented option which is supposed
to provide such information for a debugger:
`-gLEVEL'
...
Level 3 includes extra information, such as all the macro
definitions present in the program. Some debuggers support macro
expansion when you use `-g3'.
Right, but my understanding is that this is meant to allow *constants* to
be understood by the debugger. Full macro expansion is quite another thing.
Certainly, I'm all for it if it can be done, but I'm somewhat dubious.
