2000-09-25 Branko Cibej <branko.cibej@hermes.si>
* flags.h: Declare warning flag warn_system_headers.
* toplev.c: Define it.
(W_options): Add option -Wsystem-headers.
* diagnostic.c (count_error): Test warn_system_headers.
* invoke.texi: Add description for -Wsystem-headers.
* cpplib.h (cpp_options): New member warn_system_headers.
* cpphash.h (CPP_PEDANTIC, CPP_WTRADITIONAL): Don't test
CPP_IN_SYSTEM_HEADER.
* cpplib.c (do_import, do_pragma_once): Likewise.
* cpperror.c (_cpp_begin_message): Test warn_system_headers
and CPP_IN_SYSTEM_HEADER.
* cppinit.c (handle_option): Recognize -Wsystem_headers.
(print_help): Describe -Wsystem_headers.
* cpplex.c (lex_line): Reorganize condition so that warnings
about C++ comments in system headers can be enabled. Remove
label do_line_comment.
