Hi al...
I have tried to build 2.6.3-rc2-mm1 with gcc-3.4, and it works apart from this:
werewolf:/boot# modprobe emu10k1
FATAL: Error inserting emu10k1 (/lib/modules/2.6.3-rc1-jam1-gcc34/kernel/sound/oss/emu10k1/emu10k1.ko): Unknown symbol in module, or unknown parameter (see dmesg)
dmesg:
...
emu10k1: Unknown symbol strcpy
I think this solves the problem:

The strange thing is: why depmod -ae does not show any problem ?
TIA

Nope, that was not enough. Any ideas ?

Alternate fix for a similar problem I hit is appended. Basically, if
gcc-3.4 fails to inline all of them, we need to have a copy that's visible
from a module.
(Oh, the '#undef memcmp' was needed because memcmp was #defined to
__inline_memcmp so the wrong thing got EXPORT_SYMBOL'ed...)
I'll submit an extended patch that does all of string.c if people think
it's a good idea.
