[gentoo-amd64] GCC 4 CFLAGS

[Peter Humphrey]

I've started a new thread because the old one had drifted.

While trying Duncan's CFLAGS I found I couldn't emerge imagemagick because 
it didn't recognise -combine or -ftree-pre. So I removed those 
from /etc/make.conf and reran emerge imagemagick. Weirdness. Here are some 
extracts from the compilation log:

!!! ERROR: media-gfx/imagemagick-6.2.9.5-r1 failed.
Call stack:

  ebuild.sh, line 1020:   Called src_install
  imagemagick-6.2.9.5-r1.ebuild, line 90:   Called die

So I removed -rf  /var/tmp/portage/imagemagick-6.2.9.5-r1 and got exactly 
the same result!

Can anyone see what I'm doing wrong? Perhaps another C flag is pulling those 
two in.
