Re: compile/link problems on linux/ppc
Hi, It's a duplication of assembler labels in inline assembler code that is used more than once. I have fixed that in svn by using a local label instead of incmodified. Code duplication occurs because GSAtomicIncrement is used in NSIncrementExtraRefCount, which is a public inline function. Thus, the compiler generates the definition of NSIncrementExtraRefCount so that other files can call it. Furthermore the function's code is expanded inline where it is used in NSObject.m, namely in the -retain method. It compiled now and seems to work, thanks.

Re: compile/link problems on linux/ppc
I had a short look at the code and this error seems to come from the atomic increment functions for PPC. These have been changed the last time by a patch from Eric that I commited. But that was almost a year ago. What I don't understand is how this code could lead to a duplicate definition of this symbol. Could you try to have a look at the intermediate assembler file? Most likely it gets deleted before you may have a look, but you should be able to ask the compiler just to produce this file and stop compilation there.
