--- Comment #2 from Hein-Pieter van Braam <hp at tmm dot cx> --- As an aside, I think it would actually be perfectly acceptable to simple bomb during ./configure if a user tries to build gccjit.so with in-tree dependencies. Given the usecase of gccjit.so I doubt anyone would really like it if it also exports the complete symbol set for gmp, mpc and friends.
