RE: Problem with darwin_closure.S on 10.4.11/gcc 4.3.3

[Ed Mansky <mansky@mindspring.com>]

Thanks Jay, that tip was very helpful. I didn't think about the 
define coming from cc.

In my case, it is indeed __ppc__ that is defined as expected for my 
PPC 7450 G4.

I have narrowed down the issue to version 3.0.10.

I downloaded 3.0.4 of libffi. Builds fine on Darwin 8.11.0 on my G4
version 3.0.9 builds too, some warnings from ffi_darwin.c in function ffi_call.
version 3.0.10 build fails with the same errors in darwin_closure.S I 
noted earlier.

So, the code that was added in 3.0.10 to darwin_closure.S, 
specifically the SAVE_SIZE define used in LCFI1 label in the sgu 
command seems to be a problem.

I'd be happy to look into these, if anyone could point me to the 
right OSX assembler manual that has sg and sgu commands in it, that 
would be great.

For now, I'll fall back to 3.0.4 and go with that version.
