The failure of test gcc.dg/asm-fs-1.c on cygwin is a regression from gcc-2.95.

FAIL: gcc.dg/asm-fs-1.c scan-assembler-not \*_bar

The assembler output

	.file	"asm-fs-1.c"
..section	.text$*_bar,"x"
	.align 16
..globl _bar
	.def	_bar;	.scl	2;	.type	32;	.endef
_bar:
	pushl	%ebp
	movl	%esp, %ebp
	popl	%ebp
	ret
..globl _baz
..section	.data$*_baz,"w"
	.align 4
_baz:
	.long	3


With gcc version 2.95.3-4 (cygwin special) I get

        .file   "asm-fs-1.c"
gcc2_compiled.:
        .file   "asm-fs-1.c"
gcc2_compiled.:
___gnu_compiled_c:
.text
        .align 4
.globl _bar
        .def    _bar;   .scl    2;      .type   32;     .endef
_bar:
        pushl %ebp
        movl %esp,%ebp
L2:
        movl %ebp,%esp
        popl %ebp
        ret
.globl _baz
.data
        .align 4
_baz:
        .long 3

It tests that the `*' doesn't make it to the output ssembly.  Since it does, the test fails, indicating a bug in the Cygwin output macros.
