	* cppfiles.c (safe_read): Deleted.
	(read_and_prescan): New function, replaces safe_read, converts
	and/or warns about trigraphs, silently converts odd line
	terminators (\r, \n\r, \r\n).  Warns about no newline at EOF.
	(finclude): Use read_and_prescan; turn off nonblocking mode on
	the input descriptor; remove file-size-examination and
	no-newline-at-EOF gunk which is	longer necessary; be more
	careful about checking that we've been handed a legitimate
	file to read (only real files, pipes, and ttys are acceptable).
	* cpplib.h (cpp_options): Rename no_trigraphs flag to
	`trigraphs' and invert its sense.
	(trigraph_table): Declare.
	(cpp_warning_with_line): Prototype.
	* cpplib.c: Remove all references to trigraph_pcp. Define
	trigraph_table; initialize it in initialize_char_syntax.  Open
	files in nonblocking mode.  s/no_trigraphs/trigraphs/
	throughout, and invert sense.  Put cpp_warning_with_line back
	in and export it.
