Hi,

This patch provides support for offsets into .debug_loc.

The patch does not include .debug_loc support in read_tag_string_type()
as the DW_AT_string_length attribute is currently being misused by GCC
(it uses it to hold the length, rather than the location to the length)
and GDB supports the incorrect form.

There is a second part of this patch which is dependent on FORTRAN95
support of modules and will be released later.
