3a77dcde47 The brokenness in ix86_expand_clrstr is quite visible when you 
compare the function with ix86_expand_movstr.

ec9ec8af6a Gcc 3.1 (-O) now generates broken inline code for memset in some cases. 
This broke newfs (newfs left some garbage in a bitmap).

The ASM for:

	#include <string.h>
	int x, foo[100];
	main()
	{
		memset(&foo[0], 0, x);
	}

is (at least if you have fixed function alignment):

	.file	"z.c"
	.text
	.p2align 2,,3
.globl main
	.type	main,@function
main:
	pushl	%ebp
	movl	%esp, %ebp
	pushl	%edi
	pushl	%eax
	movl	x, %ecx
	xorl	%eax, %eax
	shrl	$2, %ecx
	movl	$foo, %edi
	cld
	rep
	stosl
	andl	$-16, %esp
				<-- the lower bits of `len' should be loaded
				    near here
	testl	$2, %edi	<-- this seems to be meant to test the 2^1
				    bit in `len' (not alignment of the pointer
				    like it actually does).  %edi is the wrong
				    register for holding the bits, since it is
				    still needed for the pointer.
	je	.L2
	stosw
.L2:
	testl	$1, %edi	<-- similarly for the 2^0 bit.
	je	.L3
	stosb
.L3:
	movl	-4(%ebp), %edi
	leave
	ret
.Lfe1:
	.size	main,.Lfe1-main
	.comm	foo,400,32
	.comm	x,4,4
	.ident	"GCC: (GNU) 3.1 [FreeBSD] 20020509 (prerelease)"

This seems to only result in (len % 3) bytes not being cleared, since gcc
doesn't seem to use the builtin memset unless it knows that the pointer is
aligned.  If %edi could be misaligned, then too many bytes would be set.

ee3cbef6be Make the manpage consistent with the code on the subject of comments, as to 
not change the code to always do the "GNU" thing, as it's possible people
rely on BSD m4(1) traditionally resetting comment characters in case of no
arguments to the changecom function.

e364f0da42 Fix handling of the 'noError' variable. According to the code comments, 
one can set the 'noError' variable to ignore any errors that occur for the
next command.  However, the code was only unsetting 'noError' when an error
actually occurred, so if you set 'noError', the next command completed ok,
and the command after that failed, the second command's failure would be
ignored.  This fixes this by performing the 'noError' check earlier and
then unsetting 'noError' after every command that is run.
