Hi, http://gcc.gnu.org/install/prerequisites.html says that the following two new (to me) packages are required to build gcc-4.4.0 from source: 1. Parma Polyhedra Library (PPL) version 0.10 2. CLooG-PPL version 0.15 Some questions: 1. gcc-4.4.0 and previous snapshots seem to build just fine without my having these two packages on my system. Are they REALLY required ... or just recommended? (Sort of like you did for gmp and mpfr. There were recommended for a release, and then for the next major release they were required.) 2. The Graphite loop optimizations - are they automatic if PPL and CLooG are installed in gcc ... or are they only used if you use the compile paramenters mentioned in the GCC 4.4.0 Change notes in http://gcc.gnu.org/gcc-4.4/changes.html -- Kate Minola
