Right, maybe you should not even try to support gcc 3.3 if it causes
such problems. Maybe you find nevertheless a clean workaround, I don't
know. If you need more information such as a callstack just ask ...

No sorry. I just dicovered it during my tests. For bugs you could of
course check the bug database of GNU. I'm not sure but I think it's
useless to report the bug in gcc 3.3 and hope it gets fixed (it's too
old!?) but maybe you can still just report it to get a bug number for
references.

I referred to the ZIP file you referenced in this thread (a tinyurl
one). I extracted it via a simple unzip, I cannot image that I did
something wrong. Could it be that ZIP archives do not support file
permissions at all? I don't know ...

The best solution is probably to get it integrated into sandbox. I have
no trouble with wrong file permissions for a testing version but if all
archives for the next few years will be broken I suggest to improve the
situation.
