Sorry, but-- I don't feel any particular compulsion to limit myself to
reasons that don't seem silly to you. :-)

Doubtless.  If I run into one as easy to trigger and as serious as that
one, well, I'l deal with that if/when it happens.

A good reason not to play heatseeker with compiler releases. :-)

!!  Where can I find out more?

No; last time I wrote to the gcc people, I was told I was using an
antique compiler version, even though it was the most recently NetBSD
release's version, with the implication that this meant nobody would
care.  While that was offering an improvement rather than fixing a bug,
I definitely don't feel any particular compulsion to heatseek gcc
versions just for the sake of helping *them* fix *their* bugs.

Perhaps my next project should be sparc32 support in ragge's pcc, with
sparc64 support to follow if I manage sparc32. :-~

The industry has a dire need of non-GPL versions of lots of GPL
stuff...but, admittedly, gcc is arguably the most urgent case.
