System: rn version 4.3
Patch #: 34
Priority: HIGH, if you tried to install patch #32
Subject: Patch #32 was incomplete.
From: Lots of people.  I had .3 Meg of mail this morning.

Description:
	Due to terminal brainrot I didn't ship patch 32 in its entirety.
	The variable firstbit is supposed to be declared in bits.h.  And
	it was, here.  I even tested it.  Works great.  Unfortunately I
	haven't converted rn to the newest version of my automatic patch
	generator, which would have done it right.

Repeat-By:
	Install patch #32.  Compile.

Fix:	From rn, say "| patch -d DIR", where DIR is your rn source directory.
	Outside of rn, say "cd DIR; patch <thisarticle".  If you don't have
	the patch program, apply the following by hand, or get patch.

	If patch indicates that patchlevel is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the patchlevel file to find out what has or
	has not been applied.  In any event, don't continue with the patch.

	If you are missing previous patches they can be obtained from me:

	Larry Wall
	{allegra,burdvax,cbosgd,hplabs,ihnp4,sdcsvax}!sdcrdcf!lwall

	If you send a mail message of the following form it will greatly speed
	processing:

	Subject: Command
	@SH mailpatch PATH rn 4.3 NUM ...

	where PATH is a return path FROM ME TO YOU in bang notation, and NUM
	is the number of one or more patches you need, separated by spaces.
