you probably want $(includedir)/GCC-$(version)/

The reason we did not do that in the first place, is mostly
historical: The need for versioned headers was pressing in V3 land,
but at the time no other library seemed to be in the same position as
V3, so we did feel the urge to go on colonizing other library
install machinery :-)
