The dependency list needs to be updated for all passes, not just the
last one. The dependency list is already uniquized, so it doesn't
cause problems with multiple entires.
The reasons it needs to be done for all passes is first of all that an
%include could be pass-dependent, and secondly that we only record a
dependency for an %include or %require for the first occurrence of
that file, when pathnames are resolved.

The fix for BR 3392414 introduced a fairly serious memory
leak. C. Masloch was kind enough to track down the proper root cause
and fix it correctly.

Variadic macros are really useful, even if we can only use them
conditionally.
Unfortunately this means removing -Wc90-c99-compat, because apparently
-Wno-variadic-macros is broken in gcc 13.2. Fortunately it is 2023...

Some target environments may have specific restrictions on what kinds
of relocations are possible or allowed. Allow users to opt-in to
specific warnings as to the relocations they cannot support.

NASM would try to "eat the comma token" in db expressions, even for
cases where the token was not a comma. Fix that and error out
properly.
To give better error messages, track where in the input string a token
starts or ends. This information is only valid as long as the input
string is kept, but that is just fine for error messages during
parsing.

It may be possible to generate the printed documentation from the
HTML, with a suitable combination of print-only CSS. Definitely not
there yet, though.
Exposed a bunch of problems with the autoconf m4 macro
library. Hopefulyy fix it, and tidy it up in the process.

The dependency on the warning files breaks when we are building in a
directory *and* the files already exist from being shipped with the
distribution tarballs. The make VPATH simply isn't sophisticated
enough to deal with it, so let the C compiler handle it by #including
the generated file from a dummy C file.

When converting an OUT_SEGMENT relocation to legacy, the addend is
still significant, as it would represent an explicit addend to the

"Why dup_tlist() here? We should own it."
Yes, we own it, but we still need to advance the tail pointer. Create

Add the option of having strings only conditionally quoted (&&) -- do
not quote an already quoted string again -- as opposed to always
quoting a string.
This makes a lot of the string functions way simpler to implement, and
removes the need to share ad hoc parsing code with directives.

Change the order of the arguments for %num().
Refactor the handling of optional arguments, to reduce the amount of
redundant code. This is currently only used for builtin functions, but
might be extended in the future.
