Bug 79232

Description of Problem:

Hello there,

I just tried to compile package nmh-1.0.4-15 from Redhat 8.0.

Here are some of the compiler messages.

msgchk.c:277: warning: operation on `home' may be undefined

Here is a patch which fixes the messages.

  	if (home == NULL) {
  	    pw = getpwnam (user);
  	    if (pw == NULL)
