yann@552: Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
yann@552: Set the default behavior on alpha to use -mieee since the large majority of
yann@552: time we want this (bad/weird things can happen with packages built without
yann@552: -mieee).
yann@552: 
yann@552: To satisfy those people who may not want -mieee forced on them all the time,
yann@552: we also provide -mno-ieee.
