 projects that need gcc.

 Thanks fine, but you need to acknowledge you are relying on non-standards
 compliant behaviour of gcc here, and long term that is never a good idea.

 b.t.w. if the lilypond(-devel} ports need to force the use of
 libstdc++(i.e. gcc), you probably need to indicate this in the portfiles
 with

 {{{
 configure.cxx_stdlib    libstdc++
 }}}
