--- Comment #5 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #4) > GCC builds now with the c++ which means this won't show up. Just because g++ has an implicit -lm doesn't mean that any random 3rd-party C++ compiler does too. (I don't really care about this PR though, I don't mind it being closed)
