    That's the way the Sytem V ABI PowerPC Supplement decrees it.
    thus. We ran across this while I was at LynuxWorks with our tool
    chain. Planned to make all instantiations of gcc operate the
    same, when we found this issue in the ABI.

    I believe you can set the type of ABI when you build the compiler.
    There is at least one other choice, the embedded ABI from Motorola.
    I don't happen to have a copy of that handy.
