        * mkmap-flat.awk (END):  Use pe_dll command-line arg to pass
        LIBRARY name in, instead of hard-coding it.
        * config.gcc (i[34567]86-*-pe | i[34567]86-*-cygwin*):  Add an
        extra target make frag to tmake_files according to EH model.
        (i[34567]86-*-mingw* | x86_64-*-mingw*):  Likewise.
        * config/i386/t-dw2-eh, config/i386/t-sjlj-eh:  Add new target
        frags that define makefile variable EH_MODEL appropriately.
        * config/i386/cygming.h (DWARF2_UNWIND_INFO):  Add comment.
        * config/i386/cygwin.h (LIBGCC_EH_EXTN):  Define to nothing or
        to "-sjlj" according to type of EH configured.
        (LIBGCC_SONAME):  Concatenate it to shared library base name.
        * config/i386/mingw32.h (LIBGCC_EH_EXTN):  Define to "_dw2" or
        to "_sjlj" according to type of EH configured.
        (LIBGCC_SONAME):  Concatenate it to shared library base name.
        * config/i386/t-cygming (SHLIB_SONAME):  Use EH_MODEL.
        (SHLIB_LINK):  Add missing semicolon to if-else construct.
        (SHLIB_MKMAP_OPTS):  Pass library name to mkmap-flat.awk as
        string value of "pe_dll" command-line option.
        * config/i386/t-cygwin (SHLIB_EH_EXTENSION):  New helper.
        (SHLIB_SONAME):  Use it when overriding t-cygming default.
        (SHLIB_IMPLIB):  Override t-cygming default.
        (SHLIB_MKMAP_OPTS):  Pass library name to mkmap-flat.awk as
        string value of "pe_dll" command-line option.
