This is the 2.11BSD port of the 'Vixie cron-3.0 patch1'.  
	
	Updated 1999/8/9: Fix an off by one condition in entry.c that was
	causing the 'dow' (day of week) bitmap to be overrun by one bit.
	Properly ifdef'd some rcs/sccs id strings so that they do not get
	compiled in (data space is at a premium on a 16 bit machine).  Fix
	a bug in bitstring.h (fortunately nothing uses the macro bit_alloc
	at this time) that was using 'malloc' with two arguments.  Do some
	minor cosmetic cleanup (trailing and extra blank lines, etc).  Fix
	the sigmask handling in cron_pclose() - it was using 'int' as the
	signal mask type instead of 'long' or more properly 'sigmask_t'.
	In addition to fixing the sigmask type the code was revised to use 
	modern signal and wait calls.  In crontab one of the 'swap_uids' 
	calls should have been 'swap_uids_back' in case "SAVED_UIDS" is
	supported by the system.

	The files Part01, Part02 and Patch01 were retrieved from 
	ftp://ftp.vix.com/pub/vixie/cron-3.0/ 

	In an attempt to 'mark my changes' (so Paul Vixie doesn't get
	blamed for my mistakes) this file (README.2BSD) has been created
	and the following paragraph added:

	"DO NOT SEND BUG OR PROBLEM REPORTS to Paul Vixie!    If 'cron'
	misbehaves under 2.11BSD use the 'sendbug' program OR look for the
	mail address in that script and send mail there."

	The major change made was to remove the '#ifdef' statements.
	The removal of the ifdefs was prompted by several factors:

		2.11BSD defines the symbol 'BSD' as "211".  Thus the
		datestamp based ifdefs ("#if BSD > 930811" for example) were
		wrong - 2.11 has almost all of the capabilities of later
		systems.

		2.11BSD has all but one of the capabilities ('setsid') that 
		were conditionalized on "POSIX" .  Thus POSIX could not be
		defined.  Neither could POSIX be left undefined because
		that left out too much.  Sigh.

		Conditionalized code is messy to read.

		The probability that this version will ever be ported back 
		to a 'sequent', 'convex'  or 'att' system is not at this
		time distinguishable from 0.

	Other changes include:
	
		Adding a lot more 'register' declarations (which helps
		code size - this cron is still over twice as big as the
		old one).

		Revised the Makefile and 'putman.sh' script to fit in better 
		with 2BSD's philosophy of life.

		Moved a few files into a 'grot' subdirectory to avoid 
		cluttering the main build area.  The file "diffs" is the
		summary of the changes made.
