--- Comment #17 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Martin Sebor from comment #16) > If there's no way to make profiledbootstrap work with in-tree GMP (or other > prerequisites) then it would be most helpful to change the configure script > to detect it and error out early with a descriptive message. Would be interesting to investigate why is the source file changed in between stages. Is it a generated source file?
