Yeah, the code is identical to the near version, with the only difference
being the PROC directive declaring the function as either near or far. Now, I
could either turn the function body into some kind of macro stored in a
separate file and then instantiate it from both near and far functions... or I
could just copy the original structure. Who cares, anyway.

OK, *that's* the last piece of C++ crud shared across all main executables.
According to the object in the library file though, it seems to include one
more dword named
__DestructorCountPtr

as a consequence, it doesn't even seem to be included in the games' BSS

Yup. From TH03 on, ZUN uses a different version of master.lib, containing more
features than the last official version 0.23 from May 1995. Given the relative
insignificance of the features in question, I presume that Amusement Makers
must have kept their own, improved fork of master.lib, rather than ZUN having
hacked master.lib on his own.
Anyway, that doesn't matter. In the end, we still have to reverse-engineer each
and every one of these changes, and some of the more complicated functions
won't even be reduced before the actual reverse-engineering step of this
project.

Same for registerbgifont() being a wrapper around registerfarbgifont(). But
at least there, IDA should have noticed something weird. The original delete[]
operator refers to the delete function, so registerbgifont() would have had to
be a wrapper around registerbgidriver(), which of course doesn't make sense,
