-	procedure memchr  (optimized assembler version for the 80960K series)
-
-	src_addr = memchr (src_addr, char, max_bytes)
-
-	searching from src_addr for a span of max_bytes bytes, return a 
-	pointer to the first byte in the source array that contains the 
-	indicated char.  Return null if the char is not found.
-
-	Undefined behavior will occur if the last byte of the source array 
-	is in the last two words of the program's allocated memory space.
-	This is so because memchr fetches ahead.  Disallowing the fetch 
-	ahead would impose a severe performance penalty.
-
-	Strategy:
-
-	Fetch the source array by words and scanbyte the words for the 
-	char until either a word with the byte is found or max_bytes is
-	exhausted.  In the former case, move through the word to find the
-	matching byte and return its memory address.  In the latter case, 
-	return zero (null).
-
-	Tactics:
-
-	1) Do NOT try to fetch the words in a word aligned manner because,
-	in my judgement, the performance degradation experienced due to 
-	non-aligned accesses does NOT outweigh the time and complexity added 
-	by the preamble that would be necessary to assure alignment.  This 
-	is supported by the intuition that most source arrays (even more 
-	true of most big source arrays) will be word aligned to begin with.
-
-	2) Rather than decrementing max_bytes to zero, I calculate the
-	address of the byte after the last byte of the source array, and
-	quit when the source byte pointer passes that.  Refining, actually
-	I calculate the address of the fifth byte after the last byte of
-	the source array, because the source byte pointer is ahead of the
-	actual examination point due to fetch ahead.
