>Description:
	The as31 assembler from the as31-19900126 (yes, the source
	code is from 1990!) package produces output in srecord format
	differing from that of my own old as31 assembler. The latter
	agrees with the one produced by the as31 maintained at 
	<http://www.pjrc.com/tech/8051/>.  

>How-To-Repeat:
	$cat tst.asm
        .ORG    0x0000
        mov A, R0
        ret
	
	$/usr/pkg/bin/as31 -Fsrec2 tst.asm
	$cat tst.obj
	S0030000FC
	S1050000E822F0
	S9030000FC

	$/usr/local/bin/as31 -Fsrec2 tst.asm
	$cat tst.srec
	S0030000FC
	S1060000E822EF
	S9030000FC

	Although the actual code generated is the same (this is
	generally so), the record length information in the lines
	starting with S1 is different (05 vs 06 in the second byte),
	as is the checksum (F0 vs EF in the last byte). This breaks
	applications.

>Fix:
	Replace as31 by the one maintained by PJRC.COM at
	<http://www.pjrc.com/tech/8051/>. 
	This also gets us new and improved features, and even the
	possibility of a GTK interface (which should be packaged
	separately, if adopted!).  I found the Beta 2.1 version to be
	stable, but Beta 2.2 dumps core assembling the test programs
	included with the package (srecord 2 format). They compile out
	of the box.
