I just thought that I'd see how gcc 3.3.2 (CVS) and 3.4(CVS) compared,
I was hoping (expecting) the recent months long threads on compile
performance to have had an effect... the result was a bit
disappointing...
This is the results from two LyX compiles, both xforms and qt
frontends. Identical setup: (LyX is a c++ program)
Configure line used for LyX:
./configure --without-pspell --without-apsell --disable-debug
--with-frontend="xforms qt" --enable-maintainer-mode
