* m68k.c: Include tree.h for dwarf2out_cfi_label.

        * gcc.c (process_command): Do not take address of function fatal when
        calling lang_specific_driver.

        * config/i386/cygwin32.h (DWARF2_UNWIND): Exception handling
        doesn't work with it yet, so set it to 0.
        * config/i386/xm-cygwin32.h (NO_SYS_SIGLIST): Define.

        * cse.c (cse_insn): Check for invalid entries when taking references.
More assorted pending patches.
