Cool.  I postponed writing my own long enough that I can use
someone else's!  Well, after the bugs are shaken out, that is.

There's some lint in math.c that we can clean up later.  Mostly
it needs the appended patch, and to be compiled like this:

$ iverilog-vpi math.c
[ delete a bunch of nearly innocuous warnings ]
Making math.vpi from  math.o...
$ 

Unfortunately, when I go to use the result I still get the
messages that Matt reports.  Steve, what am I missing?
