Branko Cibej 317639a81c flags.h: Declare warning flag warn_system_headers. 
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.

"... Some ctype macros are valid only for character codes that
isascii says are ASCII (SGI's IRIX-4.0.5 is one such system --when
using /bin/cc or gcc but without giving an ansi option). So, all
ctype uses should be through macros like ISPRINT... If
STDC_HEADERS is defined, then autoconf has verified that the ctype
macros don't need to be guarded with references to isascii. ...
Defining isascii to 1 should let any compiler worth its salt
eliminate the && through constant folding."
Bruno Haible adds:
"... Furthermore, isupper(c) etc. have an undefined result if c is
outside the range -1 <= c <= 255. One is tempted to write isupper(c)
with c being of type `char', but this is wrong if c is an 8-bit
character >= 128 which gets sign-extended to a negative value.
The macro ISUPPER protects against this as well." */

is bad because you may get negative offsets and thus it is not 8-bit
safe. The CTYPE_CONV macro ensures that the parameter is cast to an
unsigned char when a char is passed in. When an int is passed in, the
parameter is left alone so we don't lose EOF.
