Yes, the assembler is called with -a64, but that doesn't appear to
have the effect of defaulting to -mppc64.

[Alan: this thread is about the fact that compiling C code with "gcc
-m64 -mcpu=powerpc64" will give assembler errors, complaining about
instructions like sldi, whereas compiling with "gcc -m64" doesn't.]

Eh?  For a long time, powerpc gcc has passed "-many" to the assembler,
which should avoid this sort of problem.  Broken toolchain, I'd say.
