working kernel off RH7's gcc-2.96!?
i dont want to revisit the flame fest (at all, please) but it seems i have been using a kernel that successfully compiled under RedHat 7's gcc snapshot (2.96). i normally use gcc-2.91.66 for everything (mv kgcc gcc) but just synced my system with rawhide, so the gcc/kgcc pair is back on my system and i forgot. so i recompiled to test11 yesterday, and:
[00:05:51]rml@phantasy:~# cat /proc/version Linux version 2.4.0-test11 (rml@phantasy) (gcc version 2.96 20000731 (Red Hat Linux 7.0)) #1 Mon Nov 20 19:06:06 EST 2000
the odd thing is, not only did it compile, but my machine has been up for a day with heavy use in X with a full-featured kernel! not only no OOPSs, but no bugs!
the only thing i thought of was that alan's kgcc detection routine was in-place, and using the detected kgcc to compile but then doing a hardcoded use of "gcc" to grab the version ... but i could not find the code by grepping.
so i went ahead and removed kgcc from my path and recompiled, and sure enough -- it compiled fine.
just fyi, but someone tell me i am on crack... regardless, i am about to reboot into a gcc-2.91.66 kernel.

Just keep in mind that 'seems to run fine' doesn't clearly show cases like something in the signal handling code got miscompiled for a special case or a bit error in the file system code. You could be lucky, it might also show itself as more frequent crashes later etc.
