edb2179730 + added freeintparaloc 
* ppc get/freeintparaloc now check whether the parameter regs are
    properly allocated/deallocated (and get an extra list para)
  * ppc a_call_* now internalerrors if pi_do_call is not yet set
  * fixed lot of missing pi_do_call's

eb066d3b32 * calculate localsize also in g_return_from_proc since it's now called 
before g_stackframe_entry (still have to fix macos)
  * compilation fixes (cycle doesn't work yet though)

c70f75f1b7 * compile with -dppc603 to not use unaligned float loads in move() and 
g_concatcopy, because the 603 and 604 take an exception for those
    (and netbsd doesn't even handle those in the kernel). There are
    still some of those left that could cause problems though (e.g.
    in the set helpers)

    i386

56132c1a9c * assembler procedures now again get a stackframe if they have local 
variables. No space is reserved for a function result however.
    Also, the register parameters aren't automatically saved on the stack
    anymore in assembler procedures.
