revised duplicate-line-number elimination patch

[Nick Clifton]

Hi Geoff,

2002-04-12  Geoffrey Keating  <geoffk@redhat.com>

	* dwarf2dbg.c (dwarf2_gen_line_info): Do emit duplicate line
	numbers, gdb relies on them to detect the start of the prologue.

Approved - please apply.

Cheers
        Nick
