=begin
I do not see the real point in forcing all compilation with -O3 and it makes overriding the optimization level overly complicated. Let people choose the level they want.

=begin
The real point? gcc -O2 was a crap. We've recieved many "bug" reports that ruby cannot compile.

If you want that silly -O2 enabled, type ./configure optflags=-O2
=end

=begin
There are not that many differences between -O2 and -O3 (mainly -finline-functions IIRC) so I'm a bit surprised there. Anyway, I'd remove any "default" level to let people choose except for -O. The main problem is that if I do "CFLAGS=-O2 ./configure", it is end up with "-O -O3" (which is really -O3). Either add a "--cflags" parameter to "configure.in" or remove -O3 altogether. Your way of specifying optflags is correct of course but violates POLA in my book. Best regards.
