awesome! :-)

Couple of evenings ago I got the #ifdef/#ifndef/#else to work (and the
beginnings of the parameter-less as well as parametrized #defines).
All of the code quite a bit ugly/incomplete at this point, but so far
I am able to deal with the pearls like this:

/\
*
*/ # /*
*/ defi\
ne FO\
O 10\
20 /*
*/ 23

The parametrized macros calls that stretch multiple lines not handled
yet - but I will deal with that when I get the rest of the stuff done
- like proper parsing of the expressions within the #if.

Here's a good set of unit-tests IMHO:

Neat. Thanks!
