  alloca:
  #ifdef MOTOROLA_DELTA
  /* slightly modified version of alloca to motorola sysV/68 pcc - based
!    compiler. 
     this compiler saves used registers relative to %sp instead of %fp.
     alright, just make new copy of saved register set whenever we allocate
     new space from stack..

   * We have to copy registers, and therefore waste 32 bytes.
