Sorry not to mention that. It can (although it usually doesn't, because the default for libmpfr is to build only a static library), and this is fix by the same patch. In fact, in the gcc configury, all occurences of GMPLIBS, GMPINCS always take care of both gmp and mpfr. I followed this lead, and GMPLIBSDIR points to the directories where gmp and mpfr are installed, if different. All this is done in the toplevel configure. FX
