Both this version and the previous version had the same bug, to wit:

	lc = tolower(*name);

The 'tolower' function only works if the input was already upper case.
(at least in bsd 4.2 that's the way it is).  The line should read

	lc = isupper(*name) ? tolower(*name) : *name ;


Also, this version left trailing "0"'s on the output.  Is this right?

Perhaps someone could just post the plain english description of
soundex...

		    thanx..
