* cpplib.c (_cpp_pop_buffer): Do generate a _cpp_do_file_change

	callback even when popping the main file.

	* cpplib.c (cpp_push_buffer):  Since we no longer set return_at_eof,
	remove the unused return_at_eof parameter.
	* cppfiles.c, cpplib.c, cppmacro.c, cpppch.c, fix-header.c:
	Update callers of cpp_push_buffer.
