If I were to use a typedef, I'd put it in gdbarch.h and call it
gdb_retval_convention_t; there's nothing special about ppc-tdep.h's
needs.

The following is also legal C, Emacs-friendly, and gdb_indent.sh-friendly:

enum return_value_convention (ppc_sysv_abi_return_value
                              (struct gdbarch *gdbarch,
                               struct type *valtype,
                               struct regcache *regcache,
                               gdb_byte *readbuf,
                               const gdb_byte *writebuf));

I used this once before, but Mark Kettenis declared it "weird" or
something and asked me to take it out.  :) Be that as it may, I think
it's better than the macro or the local typedef.
