I guess you are right that reusing this stuff is too inefficient.
Bummer.  Maybe we can at least use the existing parsing mechanisms
with a special regexp for storing the information.

For lookup and storage we could use a hashtable with the macros as
keys.  Is it sensible to read this information into memory at once and
keep it there or should we rather aim for a solution where we read
necessary information from disk once a lookup occurs and free the
memory afterwards again?  Hm, maybe I should just generate such a
hashtable and look how big it is before asking such a question ...

Yes, that would be a nice surplus.
