GCC with the -std=c11 defines __STRICT_ANSI__. DJGPP checks if
__STRICT_ANSI__ is defined and if so doesn't define some things
mandated by POSIX such as struct stat, PATH_MAX, and others.
The -std=gnu11 option does not define this macro, so use it instead.
_DEFAULT_SOURCE isn't needed as no GNU nor BSD-specific functions
are used. Remove it.
Fix the last two occurrences of incorrect format specifiers for standard
fixed-width integer types.
As 444 and 555 seem to be used for no apparent reason, use the more
conventional 644 and 755.
/man is typically unused or a symlink to /share/man now, so just use
/share/man.

Note: I wanted to enable `-Og` on `develop`, but this generated warnings
(thus, errors) that aren't in `-O0`. Needs further investigation, but
annoyingly some of those are within `extern/` code, thus requiring
different flags, which AFAIK is only possible (sanely) with GNU Make.
Adds links to argument descriptions in synopsis
Adds links to man pages in the set (not to external ones)
Removes artifact from the way long opts are encoded
Makes description blurb inline, consistently with terminal output
This avoids redundancy between them (and also having to port fixes and features)
The error messages have been preserved through a string reporting mechanism
That folder contains external code, and modifying it to conform to our
code style would make applying upstream patches, amongst others,
problematic. Therefore, skip checking it.
Ideally, the folder should also be excluded from `make checkpatch`,
but I haven't figured out a way to do that yet.
Since the RGBLINK rewrite, there have been no .l files in the whole codebase
(RGBASM has the C file directly, for better and for worse)
Since flex isn't used anymore, it's a good idea to remove it from the Makefile
so people don't think it's a dependency.
The goal was to improve readability, but along the way a few things were
gained.
- Sorted sym and map files
- Infrastructure for supporting multiple .o versions
- Valgrind-proof, as far as my testing goes anyways
- Improved verbosity messages
- Added error checking
- Performance improvements, see end of commit message
The readability improvement was spurred while trying to make sense of the
old code while trying to implement features such as sorted sym and map
files.
I also did my best to remove hardcoded logic, such that modifications
should be doable; for example, "RAM loading" sections, which are linked
against a different location than the one they're stored at.
Some work remains to be done, see the "TODO:" and "FIXME:" comments.
Further, while regression tests pass, this new linker should be tested on
different codebases (ideally while instrumented with `make develop` and
under valgrind).
The few errors spotted in the man pages (alignment) need to be corrected.
Finally, documentation comments need to be written, I have written a lot of
them but not all.
This also provides a significant performance boost (benchmarked with a
51994-symbol project):

This adds two new directives: newcharmap and setcharmap.
newcharmap creates a new charmap and switches to it.
setcharmap switches to an existing charmap.
GCC has an Undefined Behavior Sanitizer (ubsan), which enables run-time
checks of undefined behaviour. It has been enabled for the `develop`
build target.
A small bug detected with it has been fixed.

Remove '-Werror' from the default make target to make it easy for
regular users of RGBDS to compile the source code. Only a few basic
warnings are left in that target.
All the warnings have been moved to a new target called 'develop'. This
target is now the one used in Travis CI to check for problems during
compilation.

-Wformat-truncation is set to 1 instead of 2 because in some cases the
return value of snprintf is used to warn about truncations but GCC still
creates a warning for it, preventing the compilation from continuing.

-Wsign-compare has been disabled because flex generates a comparison
that triggers a warning and cannot be fixed in the code.

Fix a few warnings related needed to build the source with this option.
Add new exception to .checkpatch.conf.
