 Is only the archive format unrecognized ('powerpc-aix4.3-ar tv libc.a' also 
cannot show anything inside 'libc.a') ? Or are the objects inside 'libc.a' also 
unrecognized?

 I mean that you could perhaps extract the objects inside the 'libc.a', using 
the native AIX-archiver, look them again one at a time with 'powerpc-aix4.3-nm' 
and see what it tells... This is for expecting healthy lazyness in the library 
builders -- already compiled working routines are left as they are, in the old
format... The README.RS6000 says there is a '-g' option in AIX4.3 archiver for
building old 'small' archive libraries, or you could use the GNU ar for 
rebuilding them into 'old format' libraries...

 If the library objects also cannot be looked with 'powerpc-aix4.3-nm', the 
XCOFF-format has been changed, then you are out of luck if you cannot find a 
object conversion program...

 The whole conversion idea relies on handling the libs 'just as static libs', 
the 'shared library' nature in them can still cause many problems...

Cheers, Kai
