Makefile:	Added UNIXWARE 2.x with shadow passwords from fja@extratech.com
client.c:	Made prompt appear at debug level 0. Fixed strcasecmp redefinition.
            Caused client to use set_blocking rather than making fcntl calls itself.
dir.c:		Removed redundent snum parameters.
includes.h:	Added SCO fixes.
loadparm.c:	Made default 'files to hide' a null string.
nmbd.c:		Removed O_NONBLOCK from pid file open for platforms that dont have it.
proto.h:	Changed snum to cnum where needed. Changed is_xx_path to is_in_path
            (now called via MACRO).
quotas.c:	Swapped setuid/seteuid calls when restoring uid.
reply.c:	Removed redundent snum parameters.
server.c:	Changed snum to cnum where needed. Setup new veto_list, hide_list
            namelists. Added standard_sub changes from
            Stefaan A Eeckels <Stefaan.Eeckels@ecc.lu> and
            Paul Rippin <pr3245@nopc.eurostat.cec.be>
shmem.c:	Changed cast for sizeof to be int before negating.
smb.h:		Added new veto_list, hide_list entries to connections.
            Added IS_PRINT, IS_HIDDEN_PATH, IS_VETO_PATH macros.
trans2.c:	Removed redundent snum parameters.
util.c:		Added standard_sub_basic changes from
            Stefaan A Eeckels <Stefaan.Eeckels@ecc.lu> and
            Paul Rippin <pr3245@nopc.eurostat.cec.be>
            Fixed up veto/hidden path processing so the paths are
            pres-parsed and checked for wildcards (for speed).
