89094457c5 * pass varargs float parameters only in integer registers instead of only 
in fpu registers for aix abi. Proper fix is to pass them in both, but
    at least gcc under Mac OS X only seems to use the contents in the integer
    registers currently.

cd3f064a33 + enabled postpeepholeopts phase 
+ optimize "integer op" followed by comparison of target register with zero
    to a variant of that integer op which sets the flags (ppc)
  + change rlwinm. instructions which do nothing but an "and" operation into
    andi./andis., since the rlwinm. is cracked on the G5 while andi./andis.
    isn't

bfa2301575 * const record parameters > 8 bytes are now passed by reference for non 
cdecl/cppdecl procedures on Mac OS/Mac OS X to fix compatibility with
    GPC (slightly more efficient than Metrowerks behaviour below, but
    less efficient in most cases than our previous scheme)

    behaviour of Metrowerks Pascal, which passes all const records by
