616a2ae30e Fix excessive alignment for the aout case, and unbreak genassym for that case. 
Our aout linker has alignment hacks and doesn't need gcc to do anything special.

Tested for a year by:	bde :-)

6e1cb4b9ca The brokenness in ix86_expand_clrstr is quite visible when you 
compare the function with ix86_expand_movstr.

d047bea9fd 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.

c63b7df4ec The special checks for %b and %D in rev 1.1 were done before skipping over 
any characters between the % and the [bD], so only plain %b and %B worked.
This may un-1/2ass our -fformat-extensions support.

af2650e805 MD_EXEC_PREFIX doesn't work for the cross-arch compiler. 
The change also makes the `cc -print-search-dirs' output
sane (the pre-3.1 way) in the non-cross case.
