(for testing libdwarf it's no longer so simple). Support configure --enable-wall. dwarfexample/Makefile.in dwarfexample/configure dwarfexample/configure.in dwarfexample/simplereader.c Now works with DW_FORM_GNU_strp_alt and DW_FORM_strp_sup (as well as it can) even if there is no error argument passed in to dwarf_formstring (and now dwarf_diename() and dwarf_die_text() call dwarf_formstring() so all types of string values are handled). libdwarf/dwarf_form.c libdwarf/dwarf_query.c
