I am doing this (for pentium optimized, not P2 or K6), but I triggered
gcc-2.95 optimization bugs that made the system crash at weird points,
plus I'm not getting support from here for that...

That's why I put some effort into compiling my _entire_ system with
gcc-3.2 (ports/lang/egcs/stable), and _that_ works. I have still to
use g++-2.95 because libcurses++ won't compile at all due to some
methods missing (standards compliance is a foreign word for g++-2.*),
but that still works quite well.

OTOH, I don't currently compile dynamic libraries, because
a) I'm waiting for ELF, and it's more effort to upgrade from -current
   to -mirabile again than adding ELF support
b) when I did the first compile (full make build) with gcc-3.2 I had
   some weird errors in every and any dynamically linked binary, and
   I suspect that it has something to do with /usr/lib/{lib*.so.*,*.o}
   being not in sync. I didn't really go deeper in this, but I will
   once ELF support for x86-32 is committed.

My snapshot is at http://templeofhate.com/tglaser/bsd/snap.php, if you
want to try it out. I even got XFree86 to compile. Also the settings in
/etc/mk.conf are included, plus some other nice stuff (IPv6 for apache,
etc...) but that snapshot is not for the unexperienced (OTOH I'm running
it only and it has proven quite stable).

I'd suggest you to read in the meta-faq (IIRC) why optimizing is no good
idea (the cost of gcc bugs is higher than the gain by optimizing, or even
building a custom kernel, on nowadays' computers). Then decide if you still
want to optimize, or rather stick with the official OpenBSD (remember, you
get support on this list only for official OpenBSD :) - YMMV.
