2.5.31: help2man usage

[Hans-Bernhard Broeker]

Hello, everybody,

I keep stumbling over strange things in trying to build 2.5.31 on a
DEC Alpha box running Digital Unix.  This time, it's help2man.

I didn't have that tool installed. So after I had to modify main.c
(to point it to "gnum4" instead "m4"), all builds failed because they
couldn't run that tool.  That's rather a strange thing to happen at that
point of the process, since "configure" does check for the existence of
it, and if it's not found, it should complain about it.  Instead, it
just set @HELP2MAN@ to help2man and presumed it existed.

That's not a very useful behaviour, I think.  AFAICS, if help2man is not
found, the "missing" mechanism of GNU autoconf should be used.

[Of course, I've now installed help2man, too.]
