* 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; * cppinit.c (merge_include_chains): Take a cpp_reader *. 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. (cl_options, enum opt_code): Define these from the same table, kept in a large macro. Add -fshow-column and -fno-show-column options. * cpperror.c (v_message): If show_column is off, don't print the column number. * cppmain.c: Update for new interface. * fix-header.c: Likewise.
