I didn't want to imply you were doing it intentionally; if it sounded so,
sorry.  I did not even want to say, it was a bad thing, I was simply
surprised ;)

Amazing ;)

No, it's good as it is now.  I now too moved myself to the new-regalloc
branch (I developed the ra.c based on HEAD from beginning of february),
actually I had done this, and just before I wanted to do the final
bootstrap before commiting I updated, and only expected some changes to
toplev.c ;-)  But now all is well.

np.  I'm now going to commit my pending changes, so it all is in sync.


Ciao,
