I really think that the builtin solution is the right way forward for everybody, design-wise. Thanks for doing this Richard. Pre gcc-3.4, we had the same problem with i386/i486+ separation. I think, realistically, that i486 compilation should be a minimum requirement for linux distros circa 2005. (If not i586.). Thus, the solution I will be in favor of is eliminating i386 compatibility with the version of the toolchain that first implements the atomic builtins. For people that really want to support i386, they should use gcc-2.7 to gcc-3.4. -benjamin -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14311
