of the line here. Issue -pedantic warnings for extended
directives here. Warn about K+R directives with the #
indented, and C89/extended directives with the # not indented,

to initialize speccase[] and trigraph_map[]. Delete all

* cpplib.h: Merge struct cpp_options into struct cpp_reader.
Reorder struct cpp_options and struct cpp_reader for better
packing. Replace CPP_OPTIONS macro with CPP_OPTION which
takes two args. Change all 'char' flags to 'unsigned char'.
Move show_column flag into struct cpp_options. Don't
prototype cpp_options_init.
* cpphash.h, cpperror.c, cppexp.c, cppfiles.c, cpphash.c,
cppinit.c, cpplex.c, cpplib.c:
Replace CPP_OPTIONS (pfile)->whatever with
CPP_OPTION (pfile, whatever), and likewise for
opts = CPP_OPTIONS (pfile); ... opts->whatever;

Extract CPP_OPTION (pfile, pending) and work with that
directly.
(cpp_options_init): Delete.
(cpp_reader_init): Turn on on-by-default options here.
Allocate the pending structure here.
