That's very cool. On the other hand, C can be perfectly parsed with an LR(1) 
parser. I think I did implement an LL parser too, but compared to 
implementing an LR parser, that was quite a bit less painful.

I found the following page that I think partially answered my question though (it's about why C++ can not be parsed with an LR(1) parser):
http://stackoverflow.com/questions/243383/why-c-cannot-be-parsed-with-a-lr1-parser
However, after reading the answer, I understand that the kind of compiler generator I've implemented will actually produce a GLR parser; which is capable of resolving this problem.
