That may well be, but I wasn't talking about the problem in front of 
the keyboard.

Setting (any) global CFLAGS/COPTS breaks 2.0 builds because some 
subsystems want -O or -Os or whatever but do not enforce it. OpenSSL 
was an example a few months ago. Kernels for my sparcstation 10 or my 
Quadra 700 built with -O3 blow up.

gcc 2.95.x didn't do that.
