Understood.  I didn't know that.

What then must I do to get this cross toolchain to work?  The target nm 
command doesn't understand the file format of libc.a:

/root # /usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm 
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/lib/libc.a

frexp.o:
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: frexp.o: no symbols

...

ptrgl_64_64.o:
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: ptrgl_64_64.o: no 
symbols
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: : File format not 
recognized

Thanks David.
