Hi,
ddd's inferior debugger parsing assumes a certain capitalization for
'Breakpoint'.  This fails with gdb and hardware breakpoints, where
the output is

        Hardware assisted breakpoint 1 at 0x5000000c: file main.c, line 7.

Code in PosBuffer.c then starts thinking this is a vxworks debugger
output line, and looks for a file called '0x5000000c'.

The attached patch fixes the capitalization, by omitting the initial 'b'.

        * PosBuffer.C (filter_gdb): Allow lowercase 'b' in 'breakpoint'.
        (filter_pydb: Likewise.
