IRIX 6.5 bootstrap is broken

[Mark Mitchell]

Folks --

  This part of your collective patch:

	* ginclude/varargs.h: (__va_list__): Define ifndef.
	* ginclude/stdarg.h: Likewise.

breaks the IRIX 6.5 bootstrap.  The fixed `stdio.h' file contains:

  typedef char *__va_list__;

and `__va_list__' is defined to be empty.  No joy.

Ideas?
