collect2.c (TARGET_64BIT): Redefine to target's default.

2010-04-27  Kai Tietz  <kai.tietz@onevision.com>

        * collect2.c (TARGET_64BIT): Redefine to target's default.
        * tlink.c: Likewise.
        * config/i386/cygming.h (USER_LABEL_PREFIX): Define
        dependent to TARGET_64BIT and USE_MINGW64_LEADING_UNDERSCORES.
        * config/i386/i386.h (CRT_CALL_STATIC_FUNCTION): Use
        for underscoring __USER_LABEL_PREFIX__.
        * config/i386/mingw-w64.h (SUB_LINK_ENTRY): New macro.
        (SUB_LINK_ENTRY32): New.
        (SUB_LINK_ENTRY64): New.
        (LINK_SPEC): Replace entry point spec by
        SUB_LINK_ENTRY.
        * config/i386/mingw32 (SUB_LINK_ENTRY32): New.
        (SUB_LINK_ENTRY64): New.
        (SUB_LINK_ENTRY): New.
        (LINK_SPEC): Use SUB_LINK_ENTRY instead of hard-coded entry-point.
        (DWARF2_UNWIND_INFO): Error out for use of dw2 unwind when
        x64 target is choosen.
        * config.in (USE_MINGW64_LEADING_UNDERSCORES): New.
        * configure: Regenerated.
        * configure.ac (leading-mingw64-underscores): Option added.
