Nathan Sidwell d1c566d72d libcpp: Directly peek for initial line marker
Using the tokenizer to sniff for an initial line marker for
preprocessed input is a little brittle, particularly with
-fdirectives-only.  If there is no marker we'll happily munch initial
comments.  This patch directly sniffs the buffer.  This is safe
because the initial line marker was machine generated and must be
right at the beginning of the file.  Anything else is not such a line
marker.  The same is true for the initial directory marker.  For that
tokenizing the string is simplest, but at that point it's either a
regular line marker or a directory marker.  If it's a regular marker,
unwinding tokens is fine.

	libcpp/
	* internal.h (enum include_type): Rename IT_MAIN_INJECT to
	IT_PRE_MAIN.
	* init.c (cpp_read_main_file): If there is no line marker, adjust
	the initial line marker.
	(read_original_filename): Return bool, peek the buffer directly
	before trying to tokenize.
	(read_original_directory): Likewise.  Directly prod the string
	literal.
	* files.c (_cpp_stack_file): Adjust for IT_PRE_MAIN change.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
