I know that many of these entries are bogus and need to be revisited,
but let's get the tree working again for now and then do a pass through

Delete the ifdef GPL_EMULATE case here and made the padding work for
both types of emulators so that there is no longer a need to compile
ps and friends new if you are using the GPL math emulator instead the
normal one.
