- Reimplemented the constructor/destructor invocation code for GCC.

Browse Source 
Both the 68k and PowerPC platform now invoke them in the same order
  and the 68k code uses the designated invocation priorities. The
  PowerPC destructor function now sets up the exit() jmp_buf before
  the destructor functions are called.
