Thanks Daniel.

Now, while I am able to apply your last 5 patches cleanly, I seem to
have some problems with those from:

There are three diffs:
- arm.diff : some hunks seem to exist already in CVS
- bugfixes.diff : applies mostly but not completly
- improvements.diff : applies completly

So, I know it's a pain, but can you check these once more?

Also, as far as those patches address several possibly unrelated issues:
Could you MAYBE consider to split those into single commits with an
applicable (one line) comment each? (I've had to learn that too, lately ;)

However that being said I'm not really in the mood to extract series of
patches that I don't even understand really, from dozens of emails.

So, first of all: Do you think you could ask Kirill Smelkov for commit
rights on http://repo.or.cz/w/tinycc.git and then apply your patches from
2003 (or what is left from them) on top (or below or whatever) of the
"patches-from-Daniel" branch, there?

Alternatively maybe you want Savannah CVS access, so you could work directly
to good/bad old CVS?

Alternatively other suggestions ...
