Re: djgcpp cross assembler for PPC

This means that it is not finding the correct 'specs' file to tell it to
assemble for little-endian output.

You need to add the text '-b ppc' to the gcc command line, eg 'gcc -b
ppc -gstabs -v -mlittle-endian hello.c'

Actually, I'm not sure why it was able to find the power pc executables
at all, are you sure that you un-zipped the archives into the correct
subdirectory?  And that they were unzipped with the '-d' option to
preserve directory structure?

There is more detail on installation on the downloads page,
http://www.objsw.com/download.html (scroll down the page a bit to see
the installation stuff).
