Fix problems building gold with gcc 4.3.0. * gold.h (TEMPLATE_ATTRIBUTE_PRINTF_4): Define. (gold_error_at_location, gold_warning_at_location): Use it. * configure.ac: Check whether we can compile and use a template function with a printf attribute. * x86_64.cc (Target_x86_64::do_code_fill): Swap out a 32-bit value when jumping over bytes. * object.cc: Instantiate Object::read_section_data. * debug.h: Include <cstring> * dwarf_reader.cc: Include <algorithm> * main.cc: Include <cstring>. * options.cc: Include <cstring>. * output.cc: Include <cstring>. * script.cc: Include <cstring>. * script.h: Include <string>. * symtab.cc: Include <cstring> and <algorithm>. * target-select.cc: Include <cstring>. * version.cc: Include <string>. * testsuite/testmain.cc: Include <cstdlib>. * configure, config.in: Rebuild.
