* m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro. (M4_BUILTIN_GROKS_MACRO): Rename... (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense. (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise... (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to this. * m4/m4private.h (VALUE_MACRO_ARGS_BIT) (m4_symbol_value_groks_macro): Likewise... (VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to this. * m4/symtab.c (m4_symbol_value_groks_macro): Likewise... (m4_symbol_value_flatten_args): ...to this. * m4/macro.c (collect_arguments): Accomodate changed sense. * m4/module.c (m4__module_open): Require arguments if flattening is requested. * m4/input.c (m4_push_string_finish): For now, flatten all builtins pushed as back-references. * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients. * modules/import.c (m4_builtin_table): Likewise. * modules/load.c (m4_builtin_table): Likewise. * modules/modtest.c (m4_builtin_table): Likewise. * modules/mpeval.c (m4_builtin_table): Likewise. * modules/perl.c (m4_builtin_table): Likewise. * modules/shadow.c (m4_builtin_table): Likewise. * modules/stdlib.c (m4_builtin_table): Likewise. * modules/time.c (m4_builtin_table): Likewise. * modules/m4.c (m4_builtin_table): Likewise. (mkstemp): Undo #undef hack from 2006-10-23, now that macro names are stringized without preprocessor expansion. * doc/m4.texinfo (Defn): Update comments to match reality. (Debuglen): Update test now that user macros pass builtin tokens. Signed-off-by: Eric Blake <ebb9@byu.net>
