	* src/vectors.S (__default_interrupt_vsr): Fill r15 before doing
	cyg_hal_gdb_isr call, or it might be skipped.
	cyg_hal_gdb_isr now takes PC as first argument.

	* src/ppc_stub.c:
	* src/ppc_stub.h:
	Added proper GDB interrupt support.

1998-10-27  Jesper Skov  <[e-mail]>

	* include/hal_cache.h: 
	Include HAL configuration file to be sure we get all the right
	defines. This is a potential problem, that I had thought may be
	the cause of PR 17839, but that turned out to be a config tool
	problem
