Problem with darwin_closure.S on 10.4.11/gcc 4.3.3

[mansky <mansky at mindspring dot com>]

Hi all,

I am trying to build libffi on a PowerMac G4 (ppc 7455 v3.2 dual  
867MHz CPUs) and keep getting errors in the build from the assembly  
code darwin_closure.S

The configure script, invoked with no arguments, seems to run fine  
and ends with no errors.
I do see a message near the end about a buggy sed, but get a  
directory "powerpc-apple-darwin8.11.0" as expected.

Running gmake (GNU make 3.80) then results in:

I have a copy of the Apple Mac OSX Assembler Guide (dated 2005), but  
could not find the entry for the commands "sgu" or "sg", so am unsure  
what the exact syntax should be for these assembler commands.

Where is the constant __ppc64__ defined in the code? Is it defined in  
libffi code itself somewhere, or in the OSX system headers ? I  
compared my G4 with my G5 and could not find __ppc64__ defined in the  
system headers there either.

Any tips or ideas about this would be greatly appreciated!

Thanks,
