Re: Small change in NSObject.m ASM needed for PowerPC build
Sorry, no idea, why this fails for me. "uname -a" give this result: Linux hugo 2.6.27.21-0.1-pae #1 SMP 2009-03-31 14:50:44 +0200 i686 i686 i386 GNU/Linux But I don't know what gcc relies on. I also read somewhere that you have to use the link flag "-lgcc" to use the new build in functions, but this may be for the not so well supported platforms.

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.

Re: Small change in NSObject.m ASM needed for PowerPC build
Checking the ISA reference, it appears that the required atomic instructions appeared in the 486, so -march=486 should work. I have an almost identical patch applied locally and it builds correctly with no modifications to the GNUmakefile, so I'm slightly confused as to why this fails for Fred.

Are you sure about that? Cause I've built GNUstep multiple time with the script here: http://slackbuilds.org/slackbuilds/12.2/libraries/gnustep-base/gnustep-base.SlackBuild And have never had a problem.
