I'm in the process of upgrading from the 0.9 distribution to -current.
Many Thanks to Mike Long and Werner Kuehnert for thier suggestions on
how to go about upgrading as posted to current-users.

Here are the problems I've encountered so far. If anybody has any
suggestions on them, I'd appreciate it. Especially the libg++ problem. 

lib/libc:
   o The stdio/strerror.c doesn't declare a __strerror() function, but
     the one in string/strerror.c does. So I just used the strerror.c
     in the string/ directory.
	string/: $Id: strerror.c,v 1.2 1993/10/09 00:11:01 jtc Exp $
	stdio/:  @(#)strerror.c	5.6 (Berkeley) 5/4/91

lib/librpcsvc:
   o all the .c files reference the .h files in the subdirectory src/.
     I just made all the .c files first, and then edited them by hand.
     (Yes, I know better, but what the hell.)

usr.bin/crontab:
   o the definition of getuid() in crontab.c doesn't match the one in
     <unistd.h>. (I commented out the prototype in crontab.c.)
   o usr.sbin/cron/cron.h or crontab.c doesn't include <sys/stat.h>
     for the definition of struct stat. (I added it to cron.h)
   o crontab.c references a function VFORK(), which doesn't exist and
     there isn't a #define for VFORK anywhere either. (I changed
     VFORK() to vfork().)
	/b/source/CVS/src/usr.bin/crontab/crontab.c,v 1.3 1993/05/28 08:34:33 cgd Exp

usr.sbin/iostat:
   o iostat.c includes usr.bin/vmstat/names.c which uses X_ISADEVTAB
     but that macro is defined by usr.bin/vmstat/vmstat.c and not in
     iostat.c. (I added the #define to iostat.c)

gnu/lib/libg++ and gnu/usr.bin/groff:
   o nothing compiles here, and all the modules seem to give about the
     same errors (groff won't compile either, but I think fixing this
     will solve that) I am using a -current gcc and /usr/include.
