* 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.

* 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.
