  Hello,

Normally, ABI-relevant DWARF DIEs (types and decls) should be at
namespace level.  There are real-life cases where such a DIE might be
defined in a lexical block.

This patch teaches the DWARF reader to handle such cases.

	* src/abg-dwarf-reader.cc (get_scope_for_die): Support
	DW_TAG_lexical_block as DIE scope.

Signed-off-by: Dodji Seketeli <dodji@redhat.com>
Applied to the master branch.
