The ebuild sci-libs/fftw-2.1.5-r1 has this code in global-scope: --cut-- #this one is reported to cause trouble on pentium4 m series filter-mfpmath "sse" #here I need (surprise) to increase optimization: #--enable-i386-hacks requires -fomit-frame-pointer to work properly if [ "${ARCH}" != "amd64" ]; then is-flag "-fomit-frame-pointer" || append-flags "-fomit-frame-pointer" fi --cut-- The is-flag call outputs true for my system (even when only scanning ebuilds for emerge -u world). It should be moved to pkg_setup (or similar).
Fixed
