There is also currently a bug in the GCC 3.4 C++ string class
implementation (or perhaps just the way it is compiled) on Cygwin
systems that causes trouble.  I'm not sure about the status of GCC 4.0
on Cygwin.  GCC 4.1 will be released soon.

We can't stay at GCC 3.2 forever.  Maybe it would be better to push to
have the bugs and performance problems properly fixed?

This is another problem that I think should be fixed.  I don't
understand why it has not been fixed yet, even though it has been
discussed a number of times on the Cygwin lists.  Perhaps we need
someone to offer to do the work, or provide a patch, or just continue
complaining about it until someone else does fix it, or explains
clearly why it can't be fixed.
