* c-common.h (objc_build_method_signature): Update prototype. * stub-objc.c (objc_build_method_signature): Update the stub implementation to accept and ignore additional parameter. * c-parser.c (c_parser_objc_method_decl): Reorgnize to pass the value of ellipsis to objc_build_method_signature instead of setting TREE_OVERFLOW on the parms TREE_LIST node. * objc-act.h (METHOD_ADD_ARGS_ELLIPSIS_P): New macro for accessing this field of an objc method decl. * objc-act.c (build_method_decl): Take an additional "ellipsis" argument, and set METHOD_ADD_ARGS_ELLIPSIS_P as appropriate. (objc_build_method_signature): Accept additional "ellipsis" argument and pass it to build_method_decl. (get_arg_type_list, start_method_def, gen_method_decl): Use the new METHOD_ADD_ARGS_ELLIPSIS_P instead of examining the TREE_OVERFLOW field of a TREE_LIST node. From-SVN: r98528

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
