 Have you checked the file format ?  If it really is a linker script, just as 
it tells...

 If not, do the other binutils work with it? What does the command
     powerpc-ibm-aix4.3-ar tv libc.a
say about it ?  And does the command: 
     powerpc-ibm-aix4.3-nm libc.a
find the symbols in it? These can only tell how bad the situation is... There 
is the README.RS6000 with GCC/egcs sources telling something about the AIX 4.3
archive format being extended to 64-bit etc. Reading it may tell about the 
problems with the new archive format...

 What version of binutils you are using? Do the current development snapshots 
at:

   http://sourceware.cygnus.com/binutils

work any better?

 Once I experimented with converting old Xenix/386 OMF-libraries into i386coff
format with a SCO-provided 'cvtomf' (or something) utility... It succeeded 
quite well (the last two Xenix-versions could run i386coff), so a possibility 
to make cross-tools for Xenix/386, or cross-tools for a 'minimal SCO Unix 3.2',
(using only the Xenix-subset of syscalls), was made possible... 

 So a method like the previous OMF-COFF conversion could be investigated... Is 
there a 'objcopy'-like program from IBM, which could convert the new-format 
libs (the 32-bit-ones, if separate) to the old-format, which the GNU-tools will 
recognize?  Of course I mean that one converts only copies of the original libs 
in AIX, for the cross-development purposes...

 Cheers, Kai
