Fix the one remaining site that was redirected by this. Remove the
redirection macro, so that the literal and variadic forms can have
differing types for their string field.
These are not referenced in SConstruct. messagebox.c uses C linkage for
symbols that would be referenced from a C++ file, so this has likely
been broken since the common code moved to C++.
Adjust code_window_point to use the same masks as clipping_code.
Previously, it had top and bottom swapped. However, since its output
was only ever compared for equality to 0, this transposition should not
affect the observable behavior.
Change piggy_register_sound to take the sound offset as a parameter,
rather than assuming the caller will set SoundOffset accordingly.
Remove a spurious sound reset in piggy_register_bitmap. Based on the
duplicated comment, this was probably incorrectly copied from
piggy_register_sound, where it made sense, into piggy_register_bitmap,
where it does not.
Newer gcc has become more effective at propagating values and now proves
that certain tests will always throw. This proof triggers a
compile-time error, which is desirable in the main program, but not in
the unit test. Add an indirection to hide the value from the compiler
so that it is forced to emit runtime code, which can then throw and
catch as intended.
PF_OVERFLOW is part of p3_flags, not p3_codes. Testing p3_codes meant
that the disk would be drawn when CC_OFF_RIGHT was unset. This seems
unlikely to be what was intended, so fix the mismatch by switching to
use p3_flags instead of switching the symbolic constant.
gcc libstdc++ built with -D_GLIBCXX_DEBUG includes in
std::array::operator[] an assertion of the form:
```
assert(index < size());
```
The valptridx allow_end_construction constructor, when given a
completely full array, will call operator[](size()), which causes the
assertion to fail. Rework the constructor to compute an end iterator
without using operator[]. valptridx allow_end_construction expects that
the resulting iterator may be the end iterator and shall not be
dereferenced.
Introduce a helper to obtain both the magnitude of a vector and the
corresponding normalized vector. Use it to capture both values as const
when possible.
