Somehow several arrays of compound option values ended up in
between defining menu_cmd_t and using menu_cmd_t. Reorder them.
Also, add a terminator to the list of menu commands so that it
could potentially be used manipulated from other source files
that don't have access to the array size.

We have a struct called mkroom and a function called mkroom()
so c++ complains about the mkroom() function hiding the
initializer for the struct.
Similarly, we have a struct called attack and a function
called attack().
There may be a more elegant way of eliminating those two
warnings, but renaming mkroom() to do_mkroom() and
attack() to do_attack() was straightforward enough.

It turns out that macOS barked when a POP was issued without
a prior PUSH, so since the DISABLE_WARNING_CONDEXPR_IS_CONSTANT
expanded to an empty macro on that platform.
Include a corresponding
RESTORE_WARNING_CONDEXPR_IS_CONSTANT macro for use with that
particular warning.
Microsoft and other non-GNU compilers don't recognize gcc tricks
like /*NOTREACHED*/ to suppress individual warnings. clang recognizes most
of them because it tries to be gcc-compatible. Because of that, a lot of
potentially useful warnings have had to be completely suppressed in the
past in all source files when using the non-gcc compatible compilers.
Now that the code is C99, take advantage of a way to suppress warnings for
individual functions, a big step up from suppressing the warnings
altogether.
Unfortunately, it does require a bit of ugliness caused by the
insertion of some macros in a few spots, but I'm not aware of
a cleaner alternative that still allows warnings to be enabled
in general, while suppressing a warning for known white-listed
instances.
Prior to the warning-tiggering function, place whichever one of
the following is needed to suppress the warning being encountered:
DISABLE_WARNING_UNREACHABLE_CODE
DISABLE_WARNING_CONDEXPR_IS_CONSTANT
After the warning-triggering function, place this:
RESTORE_WARNINGS
Under the hood, the compiler-appropriate warning-disabling
mechanics involve the use of C99 _Pragma, which can be used
in macros.
For unrecognized or inappropriate compilers, or if
DISABLE_WARNING_PRAGMAS is defined, the macros expand
to nothing.
