How can we upgrade the old GCC from version 3.4 to 4.1(that is from GCC 3.4 to GCC 4.1 or above) on Fedora 3 (version is 2.6.10)?
More information: We are developing an application which will be running on Fedora 3, but the application needs some atomic built-ins,__sync_val_compare_and_swap, __sync_fetch_and_add, etc, which are only available on GCC 4.1 or above. SO I think we can either define them or upgrade gcc to new one on Fedora 3, but now we don't know both.
Any help will be greatly appreciated!!
