A braced initialiser does not allow a narrowing conversion unless the value
is a constant expression the compiler can prove fits. Every site here holds a
runtime value: WORLD_COLS is the global guiWorldCols, the laptop screen
coordinates are built from iScreenWidthOffset, the sector limits come from the
externalised options. MSVC accepts all of it silently; clang rejects it, and
it is ill-formed.
Nothing about the generated code changes. MSVC was already performing these
conversions; the casts only say so out loud, at the 73 places where it was
happening implicitly.
The invariant: each site is wrapped in a static_cast to the element type the
initialiser already had, and nothing else is touched. No type is widened, no
expression is reassociated, no value is clamped or checked. static_cast rather
than a C-style cast so that a later reader can grep for the narrowings, and so
that none of these can quietly become a reinterpret_cast if a type changes.
Verification:
# every changed line differs only by inserted casts and their parentheses
git show HEAD -U0 | grep '^[+-][^+-]' |
sed -E 's/static_cast<[A-Za-z0-9_]+>//g; s/[()]//g; s/^[+-]//' |
sort | uniq -c | awk '$1 % 2' # no output
git show HEAD -U0 | grep -c '^+[^+]' # 38 lines, 73 casts
ninja -C build parse # narrowing class gone: 129 -> 91 sites
ninja -C build -k 0 # Release, four applications, green
ninja -C build-debug -k 0 # Debug, four applications, green

tiledef.h is included by 1900 objects, and each one was compiling a tentative
definition of gFullBaseTileValues rather than a declaration of it. The array
is defined once in TileDat.cpp, and every other global in the same block is
already declared extern; this one was missed.
MSVC accepts it and merges the tentative definitions, so nothing was visibly
broken. A conforming front end rejects it outright:
tiledef.h(180,12): error: definition of variable with array type needs
an explicit size or an initializer
which is what turned it up.
Verification: ninja -C build -k 0, all four applications link.

squashed into a single commit because doing it in steps that all
compiled involved a lot of boilerplate that is pointless to commit to
the repository. GH still has the PR for reference.
g_lang, MAX_MESSAGES_ON_MAP_BOTTOM, and GetLanguagePrefix() were
compile-time constants selected by the ENGLISH/GERMAN/... build
define. They're now runtime, defaulting to the same per-exe value the
define used to pick, and overridable at startup from [Ja2 Settings]
LANGUAGE in Ja2.ini.
-
XMLTacticalMessages is filled at runtime from NewTacticalMessages.xml,
never from compiled-in per-language data: all 8 per-language definitions
were the identical all-zero { L"" }. Delete them and define one shared
buffer in Utils/XML_Language.cpp (the loader) instead of pointer-rebinding
it like the static tables — this drops 9 dead 800KB zero-buffers (8
namespaced copies in LanguageStrings.cpp plus the standalone one) and
leaves no bind-ordering hazard for the XML load path.
-
ExportStrings.cpp privately recompiled one language's full text table
by #including the raw _<LANG>Text.cpp inside namespace Loc, keyed off
the exe-level ENGLISH/GERMAN/... compile macro (whichever the build
happened to select). That's redundant with the pointer globals every
other subsystem already uses (Text.h / LanguageStrings.cpp).
Drop the private copy; the unqualified table names in Loc::ExportStrings
now resolve to the global pointer externs, which BindLanguageStrings has
already rebound to the runtime g_lang by the time this runs (EXPORT_STRINGS
ini flag, checked after GetRuntimeSettings in sgp.cpp). gs_Lang (used only
by Loc::Translate for the Polish/Russian byte remap on raw .edt exports) is
now derived from g_lang via ToLocLanguage, so the export always matches
whatever language is actually active instead of a compile-time pick.
-
Editor/popupmenu.cpp and Strategic/Scheduling.cpp kept their own
call-site extern of gszScheduleActions as CHAR16[NUM_SCHEDULE_ACTIONS][20]
after the real definition changed into a rebindable pointer
(CHAR16 (*)[20], LanguageStrings.cpp). MSVC decays the outer array
dimension when mangling globals, so both declarations produce the same
symbol (?gszScheduleActions@@3PAY0BE@_WA) and the mismatch linked
silently -- but the array-typed TUs then indexed the 4-byte pointer
slot itself as string data, so the editor schedule popup and the map
schedule message text read garbage.
-
add text.def to be single-source of truth on symbol names and use it
.much simpler, less error prone if adding more strings
-
add pseudo interface for language state. MAX_SAGES_ON_BOTTOM must always
change in lockstep with g_lang. this isn't foolproof but better

.editorconfig already enforces it but it's getting changed piecemeal in
every commit. just get it done with.
the script:
```
find . -type f -not -path "./.git/*" -not -path "./.vs/*" | while read -r file; do
isFile=$(file -0 "$file" | cut -d $'\0' -f2)
case "$isFile" in
(*text*)
echo "$file is text"
if [[ $(tail -c 1 "$file" | wc -l) -ne 1 ]]; then
echo "" >> "$file"
fi
;;
(*)
echo "file isn't text"
;;
esac
done
```
