I was looking to do a workaround on a per compiler basis.
I'm looking at toolchain-funcs.eclass, and specifically
${gcc-fullversion}.  I've got a broken ebuild (dhcdbd) which requires
-U_FORTIFY_SOURCE to compile correctly with GCC 4.3.3.  But reading
tells me that I should not use this eclass to set compiler settings
directly.  Will this work, and other than the merit of the fix is there
a more desirable structure for such a solution?


inherit flag-o-matic toolchain-funcs


if [ "${gcc-fullversion}" -eq "4.3.3" ] #(or whatever the 4.3.3
$gcc-fullversion} outputs)
then    
    append-flags -U_FORTIFY_SOURCE
fi

Thanks for the help.
