2014-05-14  Bernd Edlinger  <bernd.edlinger@hotmail.de>

        Fix current cygwin build problems.
        * seh_init.c (__gnat_map_SEH): Compile also when __CYGWIN__ and __SEH__
        are defined.  Move include windows.h before system.h.
        * s-oscons-tmplt.c (DTR_CONTROL_ENABLE, RTS_CONTROL_ENABLE): Compile
        also when __CYGWIN__ is defined.  Include windef.h before winbase.h.

	* call.c (reference_binding): Treat lvalue/rvalue mismatch and
	dropped cv-quals as a bad conversion.
	(convert_like_real) [ck_ref_bind]: Explain them.
	(compare_ics): Check badness before stripping reference
	bindings.  Handle comparing bad reference bindings.
	* typeck.c (comp_cv_qualification): Add overload that just takes
	integers.
	* cp-tree.h: Declare it.
