gcc-9 rejects `std::enable_if<false,
std::integral_constant<std::integral_constant, 1> 0>::type` before it
notices that the whole expression is eliminated due to SFINAE. Use
`std::common_type` to coerce the inner integral_constant to an
appropriate integer type, which allows the expression to be well-formed
enough to reach the SFINAE check from enable_if, then be silently
removed from the overload resolution set.
Utility xrange, inspired by the Python2 feature of the same name,
provides an object that returns successive values from [start, end). It
is useful when the end index is known in advance, and is particularly
helpful when that index is expensive to recompute.
gcc-7 needs an additional cf_assert to inform it that e.idx is
constrained. Without this, it assumes e.idx could have any positive
value, then issues a fatal warning when INT_MAX does not fit in the
provided buffer.
common/arch/sdl/joy.cpp: In function 'void dcx::joy_init()':

Commit 47a6f744d split out redundant code, but accidentally stored
temporaries in a `signed short` instead of a `fix` as they should have
been. This truncated some values, causing odd results whenever
quaternions were used. Fix the problem by storing the intermediate
results in a `fix`.

Remove the fallback to Boost.Begin. C++14 is now the minimum supported
standard, and any conforming C++14 compiler should have a working C++11
std::begin.
Descent 1 mangles colors during `g3_init_polygon_model`, so this must
not be called on polygons not designed for mangling. Rearrange the
logic to allow Descent 1 to verify that polygon models are well-formed
without using the functions that mangle the colors.

The highest-level tracking code assumed filenames would always fit in a
char[9]. This was true on DOS, but has not been true in Rebirth for
many years. Builds without fortification caused silent memory
corruption in this case.
Refuse to create highest-level entries if they would cause corruption.
Log a diagnostic telling the user that this happened.
Fix original bug that buddy was limited to 5 hints per program run, not
5 per boss as it probably should have been.
Due to savegame format limitations, this still is not right. Reloading
the game should restore Buddy_gave_hint_count to its value at save time,
but will not.
Bitmaps based on grs_main_bitmap own their data. Bitmaps based on
grs_bitmap do not. Adjust prototypes to prevent initializing a
grs_main_bitmap with data it will not own.
