It's not what you asked for but I was curious about "extremely portable".

I downloaded the source from github onto a VMS system and unzipped it. I
started compiling relevant looking stuff in the common directory using just the
C compiler available at hand with no command qualifiers.  Attempts to link
suggested I needed more and it looked likely that the files in the dumb
directory would satisfy the unresolved externals so I compiled those too and
linked them in.  This made all the unresolveds go away.

Having read absolutely no documentation whatsoever and never so much as looked
at a Z-machine emulator before, within 17 minutes of starting from scratch, I
had an executable which was able to make a more than passable attempt at
running several of the files in the test directory.

None of the compiles produced any errors or informational messages - there
were just two warnings for pointer mismatches due to signed versus unsigned
chars in dumb_input.c.

I'd say extremely portable is a valid description.  It's also extremely easy
to build.

Still love that sig.
