I tried gcc.c from 
http://people.csail.mit.edu/smcc/projects/single-file-programs/ and the 
difference is a bit more noticeable:

-O0 -mno-relax-all

real	0m13.182s
user	0m12.690s
sys	0m0.450s

-O0

gcc.o is 10932968 bytes.

real	0m12.969s
user	0m12.520s
sys	0m0.410s

gcc.o is 11410552 bytes

IMHO it would still be reasonable to switch to no-relax-all, but I am 
probably not the best one to make the call.

Cheers,
Rafael
