bfd_get_symbol_leading_char instead. * coffread.c (EXTERNAL_NAME): New macro for removing possible leading character from names. (read_coff_symtab): Use BFD's FILE *, don't open a second one. (read_coff_symtab): Complain() about .bb/.eb mismatch, don't error(). (process_coff_symbol, coff_read_struct_type, coff_read_enum_type): Replace NAMES_HAVE_UNDERSCORE with EXTERNAL_NAME. * kdb-start.c (main): Remove NAMES_HAVE_UNDERSCORE. * minsyms.c (install_minimal_symbols): Replace NAMES_HAVE_UNDERSCORE. Remove SOME_NAMES_HAVE_DOT support (apparently unused). * partial-stab.h: Replace NAMES_HAVE_UNDERSCORE. * solib.c: Replace NAMES_HAVE_UNDERSCORE. * stabsread.h: Remove NAMES_HAVE_UNDERSCORE and HASH_OFFSET. * symfile.c (syms_from_objfile): Insert debugging check to test NAMES_HAVE_UNDERSCORE setting against the BFD support. FIXME, remove this (and all tm-*.h NAMES_HAVE_UNDERSCORE) soon. * doc/gdbint.texinfo (Host Conditionals): Remove NAMES_HAVE_UNDERSCORE, SOME_NAMES_HAVE_DOT, document MEM_FNS_DECLARED. (Target Conditionals): Remove all of the above.
