Re: Small change in NSObject.m ASM needed for PowerPC build

[Fred Kiefer]

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.

Really no idea,
Fred
