These now seem work both JS <-> JS and JS <-> L2.EXE.
The only issue seems to be that infinite lives mode with L2.EXE, if

This does not seem to be an issue with the JS version for some
reason, and may need to be "fixed"(?)

Mark other player as not busy anymore after hail is done, loop
through the hail menu until you leave, and retain the currently
selected option between hail menu choices.

This also enforces the "no fighting" rule, which doesn't really
need it yet since no fighting actually works currently.

Fixes issue where the "Disguise" item doesn't work as advertised,
making winning as good much more difficult.

update_space() assumed the cursor was at the correct location, but
it never was.  This caused a visual glitch when using the smackrod.

Fixes glitch when giving the guard at the bridge an apple to get to
Castle Coldrake.

If the script called from winning a battle (such as in training)

Even though https://docs.microsoft.com/en-us/cpp/preprocessor/predefined-macros?view=msvc-160 says they define it for C compiles, apparently they don't bother for C++. <shrug>

Apparently GNU forgot to include stdatomic.h in GCC 4.8.

can be shown to guests, but others (unread messages) shouldn't.

Appear to have been possible (to crash) by using a malformed text.dat file.

Nobody's checking the return values anyway.

Check return value from read().
