to bart: i believe they refer to -O2 being faster COMPILE, as -O3 is
higher optimization for speed and larger code size and longer compile
time etc. There are some fine tunings you can do to make the most out
of your time and space in all areas. check out the gcc documentation on
options that control optimization. For instance, specifying what kinds
of functions to inline.
to erik: i thought 7.1 does not use objprelink? it wasnt exactly stable...
