PEXPIRE - a subscription based expire

[Dave Taylor]

Chip Rosenthal and Mike Khaw both pointed out a couple of problems
with the pexpire() program I posted recently to "alt.sources".

Fortunately they're easy to fix:

Modifications to "Makefile":

   22,25d21
   < # if you're on a machine that doesn't have PW, then just remove this 
   < # define and see if it works (we only use it for getting the regexp()
   < # routines, which are a standard part of the BSD C library.
   < 
   27,28d22
   < 
   < LFLAGS   = 	-n
   34c28
   < 	${CC} -o ${PROGNAME} ${LFLAGS} ${OBJS} ${LIBS}
   ---
   > 	${CC} -o ${PROGNAME} -n ${OBJS} ${LIBS}

Modifications to "pexpire.h":

   25,27c25
   < #ifndef NEWSRC
   < # define NEWSRC		".newsrc"
   < #endif
   ---
   > #define NEWSRC		".newsrc"

and modifications to "pexpire.c":

   504c504
   < struct group_rec *a, *b;
   ---
   > struct group_rec a, b;
   511c511
   < 	return( strcmp(a->name, b->name) );
   ---
   > 	return( strcmp(a.name, b.name) );
   516c516
   < struct group_rec *a, *b;
   ---
   > struct group_rec a, b;
   525,526c525,526
   < 	return ( (b->is_read ? b->read_expire : b->unread_expire) - 
   < 		 (a->is_read ? a->read_expire : a->unread_expire) );
   ---
   > 	return ( (b.is_read ? b.read_expire : b.unread_expire) - 
   > 		 (a.is_read ? a.read_expire : a.unread_expire) );

If anyone has any other problems or enhancements, please drop me a
note about it!
