Does it mean that -O3 really translated into -O then making buildworld OR that 
with any optimisation higher than -O you may have _success_ with buildworld 
BUT binaries may be _broken_? I have used -O2 and -O3 with 5-CURRENT for many 
months (cvsuping to -current since 5.1-release) without any problem until 
tonight.

Thanks for your reply.
