It's a bit more than that, also TRACE=1 make
flag added to run this facility on and off
at compiling time.
Debug feature only, doesn't affect regular users.

Michael proposed to run
| sed -i -e '/^.PHONY: all/s/$/ test/' Makefile.in
since we have test/ directory. Good idea.

Apparently some people still care about compiling native on MS-DOS,
and we don't have a significant number of files which need adjustment.

Add ilog2_{32,64}() and alignlog2_{32,64}() ... the latter is intended
for alignment statements and return -1 for non-power-of-2 other than 0
(which returns 0).

Also made Makefile.in to handle dependency.
There are some makefiles in Mkfiles\ should
be fixed as well.

Merge elfcommon.h, elf32.h, elf64.h into
single elf.h -- we do support both elf32
and elf64 anyway. Let put them into common
place.

Add strlcpy() function and implementation, and use configure to detect
if strlcpy() is natively available on the system.

Hash all directives, even the ones that are backend-specific,
and instead pass the backend an already-parsed directive number.
Furthermore, unify null functions across various backends.

Move backend-specific code into the output/ directory, and make the
null debugging backend a separate file (it certainly isn't needed for
ndisasm...)

The dependency machinery relies on properly rooted includes, so give
it to them... the path syntax munging machinery in the dependency
script handles it from a Makefile syntax perspective, and then we can
hope that C compilers are smart enough to deal with forward-slash
paths even when that is not the native syntax.

Add something approaching real ELF header files.
Begin merging the common ELF code, beginning with the section name
detection.
Drop automatic generation of .comment section, and in particular the
treatment of .common as a special section (if we decide generating
.comment is still a good idea, we should just do it as a macro.)
Augment the list of known sections, and make it table-driven.

Linear searches are evil, so use an llrbtree to search for symbols by
offset. This doesn't change the preexisting behaviour that we only
look for global symbols.

Move all the version strings to a single compilation unit, ver.c; this
does not include the version macros, which are fed into macros.c.

Drop the data pointer, and instead assume the struct rbtree will be
embedded in a bigger data structure (to be extracted via
container_of()).

Implement library functions for "left-leaning red-black trees" with
uint64_t keys. This is meant for looking up symbols by address in the
backends that need to do so, e.g. ELF.
A good question is if there is a better way to do this, that recovers
the original symbol, but that's a future issue.

Add a common file, outlib.c, for output formats. Add the function
realsize() instead of open-coded variants in almost every backend.

Move the handling of "extra" macros (i.e. output format macros) into
the macros.pl mechanism. This allows us to change the format of the
internal macro store in the future - e.g. to a single byte store
without redundant pointers.
Also, stop using indicies into a long array when there is no good
reason to not just use different arrays.
Compress macros.c by representing macro directives with a single byte.
We can do this because we only use the ASCII character range inside
the standard macro files.
Note: we could save significant additional space by not having a
pointer array, and instead relying on the fact that we sweep
sequentially through the output array.
Add a builtin equivalent to the %include directive called %use.
%use includes a standard macro file compiled into the binary; these
come from the macros/ directory in the source code.
The idea here is to be able to provide optional macro packages with
the distribution, without adding complex host filesystem dependencies.
