-	procedure strcpy  (optimized assembler version for the 80960K series)
-	procedure strcat  (optimized assembler version for the 80960K series)
-
-	dest_addr = strcpy (dest_addr, src_addr)
-
-	copy the null terminated string pointed to by src_addr to 
-	the string space pointed to by dest_addr.  Return the original
-	dest_addr.
-
-	This routine will fail if the source and destination string
-	overlap (in particular, if the end of the source is overlapped
-	by the beginning of the destination).  The behavior is undefined.
-	This is acceptable according to the draft C standard.
-
-	Undefined behavior will also occur if the end of the source string
-	(i.e. the terminating null byte) is in the last two words of the 
-	program's allocated memory space.  This is so because strcpy fetches 
-	ahead.  Disallowing the fetch ahead would impose a severe performance 
-	penalty.
-
-	Strategy:
-
-	Fetch the source string and store the destination string by words
-	until the null byte is encountered.  When the word with the null
-	byte is reached, store it by bytes up through the null byte only.
-
-	Tactics:
-
-	1) Do NOT try to fetch and store 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 and convoluted body that would be necessary to assure 
-	alignment.  This is supported by the intuition that most source and
-	destination strings will be word aligned to begin with.
-
-
-	procedure strcat
-
-	dest_addr = strcat (dest_addr, src_addr)
-
-	Appends the string pointed to by src_addr to the string pointed
-	to by dest_addr.  The first character of the source string is
-	copied to the location initially occupied by the trailing null
-	byte of the destination string.  Thereafter, characters are copied
-	from the source to the destination up thru the null byte that
-	trails the source string.
-
-	See the strcpy routine, above, for its caveats, as they apply here too.
-
-	Strategy:
-
-	Skip to the end (null byte) of the destination string, and then drop
-	into the strcpy code.
-
-	Tactics:
-
-	Skipping to the null byte is Ldone by reading the destination string
-	in long-words and scanbyte'ing them, then examining the bytes of the 
-	word that contains the null byte, until the address of the null byte is
-	known.  Then we drop into the strcpy routine.  It is probable (approx.
-	three out of four times) that the destination string as strcpy sees
-	it will NOT be word aligned (i.e. that the null byte won't be the
-	last byte of a word).  But it is not worth the complication to that
-	routine to force word aligned memory accesses to be gaurenteed.
