+ * config/i386/tm-cygwin.h: Define HAVE_SSE_REGS if
+ HAVE_CONTEXT_EXTENDED_REGISTERS is defined.
+ * win32-nat.c: Define CONTEXT_DEBUGGER_DR that will also include
+ extended registers if HAVE_SSE_REGS is defined.
+ (mappings array): Add offset of extended registers.
+ (thread_rec): Use new CONTEXT_DEBUGGER_DR macro.
