On the other hand the user visible shared libs like libgomp, libgfortran, and libstdc++ are already built with -fPIC anyway. We recently also enabled -fPIC for libgcc_s.so. And now we are about to do the same for libiberty. So I think there does not remain much anyway - or am I missing something?! So I agree that removing the s390*-*-* case entirely in picflag.m4 will be the better way to fix this. We then also should revert that one: http://gcc.gnu.org/ml/gcc-patches/2011-11/msg00643.html Bye, -Andreas-
