This is mainly curiosity but... when I compile kernel sources they go
just fine, but if I change the optimization level -O2 to -O3 in the root
source Makefile it does NOT success in making modules part. The error
that it gives is:
make[2]: Cambiando a directorio `/usr/src/linux-2.4.19-8mdk/fs/smbfs'
gcc -D__KERNEL__ -I/usr/src/linux-2.4.19-8mdk/include -Wall

Can anyone explain WHY???
