I'm very conservative in upgrading my development tools.  As long as
something works fine for me, I'm reluctant to do significant upgrades,
because doing so runs a risk of destabilizing the development
environment, and with so little free time, I cannot afford that,
unless strictly necessary.

A DJGPP port of GCC 4.3.2 is available since Sep 2008, but I dislike
GCC 4.x because it whines too much about perfectly valid C code.  (It
may not be a problem with GDB sources, but I compile other projects
besides GDB.)  So, if GCC 3.4.4 solves the problems I have, I won't
have a significant incentive to go to 4.x.

If 3.x won't help, then I might do just that.

Thanks.
