Free more token memory for re-use
It now re-uses the '#' token for all preprocessor lines,
and the 'define' token itself (even though it obviously
can't free the tokens from the definition).
This makes the 2004 IOCC entry a non-issue memory-wise.
Now I just need to speed up the parser. Sixteen seconds
on pre-processing is not acceptable..
