[Tinycc-devel] Sample patch from Mercurial repository

[KHMan]

Hi all,

Attached is a sample patch based on the Mercurial repository. I
assume revisions up to 395 is already in the official CVS, so
perhaps I shall try and see how many trivial patches I can make
from revision 396 onwards, versus current Savannah CVS. No quality
assurance beyond trying a "make all" on Ubuntu. Comments?
