cygming.h (DWARF2_UNWIND_INFO): Error build when TARGET_BI_ARCH is specified without enabling SJLJ. 

2009-07-24  Kai Tietz  <kai.tietz@onevision.com>

        * config/i386/cygming.h (DWARF2_UNWIND_INFO): Error build when
        TARGET_BI_ARCH is specified without enabling SJLJ.
        * config/i386/mingw32.h (MD_UNWIND_SUPPORT): Define MD_UNWIND_SUPPORT,
        if TARGET_64BIT and TARGET_BI_ARCH aren't defined.
