[1] ofppc/pegasos has issues with symtab loading.
sandpoint works fine in multi-user, found an annoyance by com(4) change.
[2] weird failures.
[3] relocations fail in libgcc
[4] cc1 gets segv compiling libgcc.
[5] mips*eb kernels seem to work as well as gcc 4.5 ones.
[6] ia64 port is missing libc, libkvm and more support. libgcc has some uncommited hacks.
[7] m68k/vax/sh3 gcc seem to randomly get -fstack-protector/-Wstack-protector
wrong, for example m68k flags alarm() as unprotected in
libc/gen/alarm.c:53, vax ifinit() in sbin/routed/if.c:680.
--> hacked around
[8] LOONGSON kernel has general problems
[9] no kernels in evbcf port yet
