  <cite>Reload is the GCC equivalent of Satan.</cite> Oh, yeah,  
great! ;-)

  The "bug" was:

enum { REG1, REG2, .. , REG96, num_first_pseudo_register };
#define FIRST_PSEUDO_REGISTER	num_first_pseudo_register

  This code is compiled by gcc, but the generated compiler fails  
during register allocation.

The correct code is:
#define FIRST_PSEUDO_REGISTER	96

  This is a little bit unexpected.
