Log message:
	1998-10-28 16:10 -0500	Zack Weinberg  <zack@rabi.phys.columbia.edu>
	
	* c-lang.c: Declare extern char *yy_cur if USE_CPPLIB.
	(lang_init): Call check_newline always.
	* c-lex.c (init_parse) [USE_CPPLIB=1]: After calling
	cpp_start_read, set yy_cur and yy_lim to read from
	parse_in.token_buffer, so that we'll see the first #line
	directive.
	* cpplib.c (cpp_start_read): finclude the main input file
	before processing -include/-imacros.	 Process -imacros and
	-include separately, and handle -include by stacking a
	buffer for the file in question as if it'd been #included.
	* toplev.c (documented_lang_options) Recognize -H when
	USE_CPPLIB is on.
	
	1998-10-28 16:09 -0500	Zack Weinberg  <zack@rabi.phys.columbia.edu>
	
	* cpplib.c: Merge do_once into do_pragma.  Break file handling
	code out of do_include.
	Move append_include_chain, deps_output,
	file_cleanup, redundant_include_p, import_hash,
	lookup_import, add_import, read_filename_string, read_name_map,
	open_include_file, finclude, safe_read to cppfiles.c.
	Move prototypes for deps_output, append_include_chain,
	finclude to cpplib.h.  Move definition of struct
	file_name_list there also.
	
	* cppfiles.c: New file.  Contains all the above functions
	broken out of cpplib.c; also hack_vms_include_specification
	from cccp.c and find_include_file, a new function broken out of
	do_include.
	
	* Makefile.in (cppmain): Depend on cppfiles.o.
	(fix-header): Likewise.
	(cppfiles.o): New target.
	* configure.in (--enable-c-cpplib): Add cppfiles.o to
	extra_c_objs.  Add ../cppfiles.o to extra_cxx_objs.
