ecd4e81a7c Fix Makefile and some unneeded #includes. 
make clean would first compile everything before cleaning.
And building anything would make git-info.h too late.

9d756361b4 Fix pasto, present since all recorded history. 
I don't think it made any practical difference: 2, like 1, is >= 1 and
that is what all the tests of xxx_PREC test.

80b20b17eb Add some info about git commit when printing the version. 
Also modify dependency generation to be a side-effect of compilation.
It's still not quite perfect in picking up some changes (in particular
just after a commit, no files have changed but the git identification
is now different).

ce2d526291 Added some robustness for when dumpobj is run on files which are... 
almost an object file, such as an object library.

0aee873dc8 Add the link checker tool (in Perl). 
This tool tells you which symbols are referenced by a group of OBJ files
but not defined.

It uses dumpobj to parse the OBJ files.

137a9db671 More tests. Refine string delimiter test for .ASCII a bit. 
Make the delimiters for .INCLUDE and .LIBRARY accept the same
delimiters (= is not disallowed, it just makes the line look like
an assignment).

c423ee346a Handle invalid expressions in .WORD directives with a message. 
This is most relevant in implied .WORD directives which are caused by an
attempt to call a macro (which happens to be undefined) with arguments
that don't parse as valid expressions.

60d0afde00 Use the path search also for .INCLUDE, and add -I option: include path 
The -I option is used to specify the search path for .INCLUDE files.
It also appends this to the "INCLUDE" environment variable.

d38f4009c4 Crank up the warning levels, and adjust the code to silence ... 
several compilers:
- gcc version 4.5.3 (NetBSD nb2 20110806)
- gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)
- Ubuntu clang version 3.6.0-2ubuntu1 (tags/RELEASE_360/final) (based on LLVM 3.6.0)

The warnings were mostly about local variables shadowing others,
unused function parameters, and C++ style comments. Some variables were
indeed used before set.

Note that on Linux, using -std=c99 does stupid things like *remove* the
declaration of strdup() from <string.h>. Therefore I've reluctantly used
-std=gnu99.

435cdb0b7f Separate out the string parsing for .include/.library file names and macro arguments. 
They behave observably different from generic string parsing and trying
to account for them generically just gets in the way.
.rept is treated the same as a macro.

536d1856f0 .IF B,< > is supposed to be TRUE

60af942129 .RESTORE restores DOT too 
this is how it should be according to page 6-42 of the manual.
Kermit does this ugly thing to backpatch some .word value:

     435 000070                         	dial$time	35.
       1 000070                         	modval	35.,dial.time
       1                                	.save
       2 000070                         	.psect	modinf
       3        000006                  	. = $$current + dial.time
       4 000006 000043                  	.word	35.
       5 000070                         	.restore
     436 000070                         	wake$string	<^E^M>

where the current program section already is modinf. So the .save stores
DOT, it's changed to a lower value (6) to backpatch, and .restore sets DOT
back to 70.

8433503792 Make sure that undefined global symbols don't get reduced to 0 when negated 
Test case:

        ; test complex relocations

        ; .globl  IE.ITS,IE.MON ; implicit
        mov     #-IE.ITS, space

space:  .word   IE.ITS    ; the only simple relocation
        .word   -IE.ITS   ; all others are complex relocations
        .word   ^C<IE.ITS>
        .word   IE.ITS + IE.MON
        .word   IE.ITS - IE.MON
        .word   IE.ITS * IE.MON
        .word   IE.ITS / IE.MON
        .word   IE.ITS & IE.MON
        .word   IE.ITS ! IE.MON
