Hi, GCC now requires ISL and a very new CLOOG but download_prerequisites does not download those. Also, there is only one sensible place to call this script from, so check for that. Also, factorize a bit the code.
Tested by using it in the the GCC Compile Farm. I tried to build and install CLOOG and ISL by myself into /opt/cfarm/ but that breaks in some strange ways. Using the script, bootstrap works just fine. In some dream universe, configure would detect that the prerequisites are missing or incorrect very early, give a sensible message and suggest to download them automatically, and then just do that. OK for trunk? Cheers, Manuel.
