Changes to ALN:

10/12/91
1) LNR would put out a bad .lnk file when it encountered static data
(i.e., data declared with the 'static' keyword in C).  When the bad
.lnk file was given to aloc, aloc would abort with a fatal error.

2) LNR would abort if it was given more than ~17 files to link.

3) In some situations LNR would put out a bad .lnk file if RDB debugging
information was desired, which aloc would subsequently reject.

10/22/91
4) LNR would exit w/ an error if it encountered control characters in
a -f file (including ^Z, which some editors put out at the end of a
file).

11/19/91 mapfile.c *jd
	lnr was only outputting \n to map file, not \r\n. 
	added code to pm_putchar to add the \r when passed \n.

11/20/91 debug.c *mks
	lnr was putting out bad index fields in the debugging records

1/10/92 MWS
	Changed name from lnr to aln to be consistent with the rest of the
	ROM tools.  So, we've now got aln, aloc, and ahex.

1/16/92 azpass2.c MWS
	Modified expression fixup code so that SUB expressions with
	two symbols will work.  i.e.:

		Expr SUB
            GBLSYM 0, endtbl
            GBLSYM 1, ledxref

	The only reason this works is because SUBS of this type always turn
	out to be constants.  In other words, the #$%!@ assembler should be
	doing this itself.

2/10/92 pass1.h MWS
	Modified 'Data_seg' segment definition to reserve 2 bytes at the beginning
	of the Data group.  This makes it easier to catch NULL-pointer write
	bugs, and also matches what ln does.

4/9/92 ------------------	Released v5.2a beta 1 ---------------------

8/26/92 omffile.c jd
	changed omfinit() to compute acbp field in segdef records, so that
	segment alignment codes work

8/28/92 alnmain.c jd
	When generating output file name from first input name that includes
	a path having dots (e.g. ../foo.o), aln didn't generate correct output
	name.

9/3/92 pass1.h *jd
	aln leaves 2 unused bytes at beginning of _data (aka dataseg) segment,
	but wasn't adjusting size of segment for those bytes

10/4/92 ------------------	Released v5.2a beta 2 ---------------------


10/12/92 jd: link.h
	aln was creating invalid fixup records, because it was creating LEDATA
	records that were longer than the maximum 1024 byte length.

10/12/92 jd: seglook()
	aln was not gathering together segments in the same class, but this
	is required by rdb (it expects all code symbols to be grouped together
	in the .dbg file, followed by the data symbols). aloc could handle
	this separation of segments, but not rdb.


10/19/92 jd: getval()
	aln was not correctly processing the DATAREF, CODEREF, and BSSREF
	loader items, which are generated when sqz optimizes the object module
	libraries.

10/28/92 jd: omf_fixup()
	aln was not generating the correct offset for a fixup record that
	referenced the first data bytes of the previous LEDATA record

11/10/92 jd: outrecord(), omf_fixup(), outbyte(), RecordAlmostFull()
	Added code to flush omf record buffer when it's almost full
