2007-10-16 Nick Clifton <nickc@redhat.com>
* configure.in (--enable-elf-stt-common): New configure
option. If enabled then the tools can generate symbols with
the ELF STT_COMMON type.
* config.in: Regenerate.
* configure: Regenerate.
* elf.c (swap_out_syms): If USE_STT_COMMON is defined then set
the type of emitted common symbols to STT_COMMON.
* elfcode.h (elf_slurp_symbol_table): Accept STT_COMMON symbol
types.
2007-10-15 Alan Modra <amodra@bigpond.net.au>
* coff-arm.c (arm_emit_base_file_entry): Check fwrite return value.
