Does `-O6' really do anything, or is `-O3' the highest real
optimization, as according to the `gcc 2.7.2' info? I need to get
docs for `egcc'.
-O6 does nothing more than -O3 for GCC (2.7 and 2.8) and EGCS. It
does do something with the Pentium GCC[1]. When -O6 works (much of the
time) it makes things wonderfully fast.
