	* cppinit.c (cpp_init): Set global flag when called.
	(cpp_reader_init): Bomb out if cpp_init hasn't been called.

Sun Aug 20 01:41:35 MSD 2000 Dennis Chernoivanov <cdi@sparc.spb.su>

        * cpplex.c (cpp_scan_buffer): Move `output_line_command' just
        before `process_directive' so that newlines won't be missed
        for directives.
        (cpp_printf): Increment `print->lineno' when newline is emitted.

        * cppmain.c (cb_ident): Likewise.
        (cb_define): Likewise.
        (cb_undef): Likewise.
        (cb_include): Likewise.
        (cb_def_pragma): Likewise.
        (dump_macros_helper): Likewise.

	* gcc.dg/cpp/pragma-1.c: New test.
	* gcc.dg/cpp/pragma-2.c: New test.
