Using the same approach in gcc/config/darwin9.h reveals that Xcode 3.1.4 still
produces three types of warnings from dsymutil. These are of the form...
warning: DWARFDebugInfoEntry::AppendDependants() -- check on this item
TAG_subrange_type: attr = AT_upper_bound form = FORM_ref4^M
warning: DWARFDebugInfoEntry::AppendDependants() -- check on this item
TAG_subrange_type: attr = AT_upper_bound form = FORM_ref4
arning: {0x0000026d} TAG_variable: AT_location( 0x00000000 ) didn't have valid
function low pc, the location list will be incorrect.
