Log Message:
        
        * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
        Protect definitions from macro expansion under -DNDEBUG by
        parenthesising the expanded function names.
        * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
        (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
        (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
        (m4_is_syntax_macro_escaped): Similarly protect function
        definitions from macro expansion under -DNDEBUG by #undefing the
        matching macro names before each definition.  Also, move all the
        function definitions to the end of the file so that any
        invocations in the rest of the file pick up the fast macro
        versions.
        * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
        (m4_set_debug_file, m4_set_trace_messages)
        (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
        (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
        (m4_set_max_debug_arg_length_opt): New fast macro versions of the
        option setter functions.
