I can live with this.  Everything is "--with-xxx" by default, but can not
be built in by using "--without-xxx".

Would it be acceptable to move the code for these to a new directory, say,
src/modules?  Something along the lines of...

src/modules/geometric
src/modules/ip_and_mac

This would allow for each type to have a pg_proc.h, pg_type.h, etc.  Much
cleaner than #define'ing the heck out of the existing include files.  The
geometric/pg_proc.h would contain the entries from pg_proc.h.  Then there
would also be a .sql file that contains the necessary commands to load
the module if it was not compiled in or was just needed in one database.

Forcing someone to re-compile to use module would seem to go completely
against the extensibility side of postgres.

I think once there is one thing there as a module, it will serve as an
example for others.  A simple example would be the cash/money code. Add
an indexing method to it and it would be a brief but complete example.
