The formatting doesn't follow the GNU coding standards, and the real issue with this patch is that there are a lot of systems out in the world that use 64-bit long double still. I mentioned last week on gdb@ and binutils@ that I think we need a way to mark the ABI used by PowerPC binaries. That would easily cover this also. I'll be thinking about it more next week. -- Daniel Jacobowitz CodeSourcery
