The existing code will break at runtime, rather than link time, on an 80486 and earlier, and so I assume (from the fact no one has complained) that no one is using GNUstep on a 386/486.Well, how old is that code? Up to about a year ago I built and used GNUstep on a 486-class machine, although the CPU was not genuine intel but a compatible processor which was based on 488 ISA, it did work...
As I said in my other email, I was mistaken about when the atomic ops were introduced. They should work with -march=486, not just - march=586 - it works for me with no manually-set CFLAGS or modified GNUmakefile, on GCC 4.2.
