23b867b7a4 Handle file position information for fragments differently: Instead of 
handling them separately (which has historic reasons), generate real line info
information. This means that line info for the assembler source will be part
of the debug info file.

2bb2d97ab0 Fixed and improved the code for compares. Before, compares of chars to a

d54ca88743 Added a new option --dep-target to the compiler. This option allows to set the 
target in the generated dependency file. The cl65 utility will use this option
to override the depdendency target, if actual object files are to be generated
from C input. So the generated dependency will not have the intermediate .s
file as target, but the final .o file, which allows to use the dependency
files without further processing.

96cf7f6271 Changed generation of makefile dependencies: 
* There are now two options, --create-dep and --create-full-dep. One
    will add system includes, the other not.
  * Both options require a file name. This is an incompatible change(!)
    but has the advantage that the user is in control of extension and
    path of the generated file.
  * Output will always include a phony target for the input files. This
    may not work with all make programs.

ff4eeebec2 Makefile patch contributed by Greg King: 
I added the "MAKEOPTS=" to the top-level "gcc.mak" that he wants, and I
changed the tool source tree's top-level make-file so that it supports
parallel building.  (I added a rule that builds the common library before
building anything else.)

6078953baa Do not use a separate byte for an END opcode, instead place the bit into the 
previous opcode. This saves one byte per character with the exception of
characters without a vector representation, where we loose one byte, because
we need to add a dummy vector just to apply our END bit.
