This is a re-post of a patch posted earlier. Apparently, it never
made it out of our country; every now and then there seems to be
a major lossage of news at our national or continental backbone.
This patch takes care of a bug in some MicroSoft C implementations of
the sscanf() library function that causes the pc-mail programs to
believe there is more unread mail than there actually is. This problem
definitely does not occur on the UNIX systems that I tried the software
on (SunOS 4.0.3 and MicroPort System-V/AT 2.3).
In order to apply the patch, cd to the `main' subdirectory and feed
this article to the patch command. If you do not have the patch program,
the changes are quite straightforward and can easily be applied by hand.
