So does the installation of GCC-4.4 require a GMP >4.3 ? , if so then to get it to use MPIR all we need to do is bump our gmp compatibility version numbers from 4.2.1 to 4.3.1 , assuming we have implemented any new documented features. > I don't know where the original system gmp is (or even if there was > one) since the only other files o nthe system called gmp.h are in > sage-*/local directories.
