This cannot happen, unless gcc is linked statically (which is not the case for Slackware 14.0, I just checked), since cc1 uses libgmp. Maybe something goes wrong when a kind of libgmp-dev (with pkg-config stuff) is installed, and "stupid libtool (or pkg-config)" finds something it shouldn't. I cannot replicate in any case (with or without libgmp-dev) for Debian or Suse. Since I am new to Slackware, I need to figure out what libgmp-dev equivalent is (if it exists).
