Commit a7a4fd17 by Fred Fish Committed by Jason Merrill
Options

beos-elf.h (STARTFILE_SPEC): Add i386-mcount.o when user gives -p option. 

        * config/i386/beos-elf.h (STARTFILE_SPEC): Add i386-mcount.o
        when user gives -p option.  Add init_term_dyn.o for BeOS 5.0
        and later.

        * config/i386/beos-elf.h (INCLUDE_DEFAULTS): Add additional
        Be directories to search path.

        Remove support for __declspec(dllimport) and __declspec(dllexport).
        This is leftover cruft from the earlier BeOS gcc port when BeOS
        used Microsoft's PE object file format.
        * configure.in (i*86-*-beoself): Remove extra_objs=winnt.o.
        * config/i386/t-beos (winnt.o): Remove Makefile frag.
        * config/i386/beos-elf.h (TARGET_NOP_FUN_DLLIMPORT): Remove.
        (VALID_MACHINE_DECL_ATTRIBUTE): Remove.
        (VALID_MACHINE_TYPE_ATTRIBUTE): Remove.

        (STRIP_NAME_ENCODING): Remove.

        Remove support for obsolete version of BeOS that is no longer
        supported by Be.
        * configure.in (i*86-*-beospe*): Remove.
        * config/i386/beos-pe.h: Remove.
