I chose ghdl as my first ebuild to update (in hopes of eventually contributing more significantly to Gentoo). The reason I mention that is that the gnat-gcc package is not up-to-date and (as I've learned before posting here) doesn't compile C or C++ (it's compiled with --enable-languages=c,ada but there are problems with standard headers), so I think it is not meant to be able to compile C code. gnat is my second target (that one is trickier because the majority of the work is in the gnat.eclass and gnatbuild.eclass so I need to read up on eclasses). I've opened bugs on the Gentoo bugtracker and will try to update gnat-gcc, but for now, it is not straightforward to use for the purpose of building ghdl. Thank you for your help. Olivier
