Bugzilla Bug 8843

I have recently installed a fresh 1.4rc1 on my P4 box. Everything emerged fine
except kdeaddons 3.1beta2 which is producing an odd error, it ends up with:

I am using gcc 3.2 (extracted from the Pentium4 stage3 ball), my flags are as
follows:

CHOST='i686-pc-linux-gnu'
CFLAGS='-march=pentium4 -mcpu=pentium4 -O3 -pipe -fomit-frame-pointer'
CXXFLAGS='-march=pentium4 -mcpu=pentium4 -O3 -pipe -fomit-frame-pointer'

config.log file generated by the ebuild

This is the same as bug #7625, only that was reported for kdeaddons 3.0.3. It  
was fixed by not allowing -march=pentium4 and -sse2 to be used together. 
However the fix was only added to the 3.0.x ebuilds because noone confirmed it 
for the 3.1.x. tree at the time. Now that you have, I'll add the fix to those 
ebuilds as well. Will commit in a few minutes, please tell me if it helps. 

Thanks, it is making somehow further now and fails at a later stage. Please see
below what it ends up with, I am attaching the lates config.log as well.

config log with updated ebuild

Um, your second error log is identical to the first one AFAICS... Are you sure
you posted the right thing? 

Yikes, you are right. I did emerge rsync, commented out the mask, deleted
/var/tmp/portage/ to make sure I am using the newest ebiuld. Same result. 
I tried another thing, changed my flags to '-mcpu=i686 -O3 -pipe' to see if it
compiles with these. Unfortunately configure failed because it could not find Qt
(using my original p4 flags it finds it). Quite strange.

The answer to that (configure not finding qt) should be in the config.log for  
 that configuration.        I found the reason for it failing in the same way
again. I forgot to add  inherit flag-o-matic to the changed ebuilds, so their
call to is-flag() didn't do anything. I've fixed it now, please test once the
new version hits rsync. 

The new ebuild compiled smoothly :) Thanks a lot Dan!
