[PATCH] use fileline typedef

[Per Bothner <per at bothner dot com>]

This fixes three cpp* files to use the fileline typedef when
appropriate.  There are certainly more in other files.  (Once we
have fixed most of them, then I'd like to define fileline as a
struct type when ENABLE_CHECKING is selected, so we can catch
incorrect usage.)

I checked this into the trunk.  I had earlier (08-21) checked it
into the compiler server branch.

2003-08-26  Per Bothner  <pbothner@apple.com>

	* cpplib.h (struct cpp_token):  Change type of field line to fileline.
	(cpp_error_with_line):  Use fileline for appropriate parameter.
	* cpphash.h (struct cpp_macro):  Change type of field line to fileline.
	(struct cpp_reader):  Likewise for fields line and directive_line.
	(_cpp_begin_message):  Use fileline for appropriate parameter.
	* cpperror.c (print_location, _cpp_begin_message, cpp_error_with_line,
	cpp_error):  Use fileline for appropriate parameters and variables.
	(print_location):  New local lin, since it is not a fileline.
