If that is strongly needed, the SFE project could try to add support to the gmp lib for older CPUs. BTW: with packages in SFE, you are always free to recompile the packages with different switches. Everything is open and done in a way that enables all users to recompile. The spec-files used in OI-SFE are kept in sync as good as possible between the SFE svn repo and the repository copies used for OI-SFE. About which compiler version to use. SFE follows the path to use its own gcc copy (4.6.3 currently) and tries to stay away from gcc runtime libraries the OS provides. That way the OS can update the compiler almost independently from SFE and vice versa. That is an advantage in large projects where you have less chance to synchronize everything. In SFE we've seen several times that some of the packages need a more fresh version of the compiler and some need the older gcc. In practise most of the packages work with all compiler versions, but we've seen that it helps to actually use both compilers in parallel for a while. Even within SFE we can use gcc 4.5, 4.6.3, 4.7.x in parallel and the componenty compiled find the right runtime libs. If one copies the SFE gcc implementation, then one would design the compiler packages in a way so that different versions can be used at the same time. Just compile your actual work with the gcc version that works and save time+effort and not burn days and weeks on patching sources. Alignment to a single compiler version can be done later once you have time or the source code in question got better. For gcc 4.4.4 that one would compile the core OS, for stuff on top the other sub-projects would use a more fresh compiler version, preferably have say 4.6.3 at hand and latest+greatest 4.7.x for selected C++ stuff.
