+ procedure strpbrk (optimized assembler version: 80960K series, 80960CA)
+
+ char_addr = strpbrk (string, brkset_string)
+
+ Return the address of the first character in string that is NOT
+ in the brkset_string. Return NULL if none exists.
+
+ At the time of this writing, only g0 thru g7 and g13 are available
+ for use in this leafproc; other registers would have to be saved and
+ restored. These nine registers, plus tricky use of g14 are sufficient
+ to implement the routine.
+
+ This routine stays out of g3 and g4 altogether. They may be used by
+ the strtok routine, which calls this routine in an incestuous way.
