I first saw it in groff 1.17--I have no idea why it was there (it wasn't in
groff 1.11, but I have no record of intermediate versions).  A quick check
of the MSVC documentation indicates that it's only needed for the is*(),
and to*(), and getch() functions and macros.

The latest version seems to build just fine using MSVC 6.0 without ctype.h.
I don't have time right now for extensive runtime testing, but I can't see
why there would be a problem.
