Thats all taken care of, what apparently is a problem at least for
Alexander is that there seem to be no dependencies from files that
actually use the generated ones (like phpast) to the generated files. So
it seems that sometimes these files (like main.cpp from the parser) are
being compiled before the parser-generator is run which then causes an
error.
