How about using the flags used for Fedora Core at least? I can't find where I read about 
them though.


However OpenMP was not available to GCC sometime ago (that is when VS 8 .NET was under 
development and I checked MINGW32/GCC at that time), no compile problem of course since 
unknown #pragmas are ignored. So if GCC doesn't provide OpenMP yet, it may compile, I 
think the SMP of SL 5 may suffer, and perhaps bugs/incompatibilities may be introduced 
(for example gcc-specific or other multithreading code may make wrong assumptions about 
OpenMP based code, or interoperate with one another etc).
