        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.
