2002-02-04 Elena Zannoni <ezannoni@redhat.com>

	* gdbarch.sh: Add definitions for COFF_MAKE_MSYMBOL_SPECIAL and
	ELF_MAKE_MSYMBOL_SPECIAL.
	* gdbarch.c, gdbarch.h: Regenerate.
	* arch-utils.c (default_elf_make_msymbol_special,
        default_coff_make_msymbol_special): New functions.
	* arch-utils.h (default_elf_make_msymbol_special,
        default_coff_make_msymbol_special): Export.
	* elfread.c (elf_symtab_read): Compile use of
	ELF_MAKE_MSYMBOL_SPECIAL unconditionally because it is now
	multiarched.
	* coffread.c (coff_symtab_read): Ditto, for
	COFF_MAKE_MSYMBOL_SPECIAL.
