* libc/include/sys/features.h: Redefine compilation environment
	definitions for Cygwin to cover 64 bit Cygwin.
	* libc/ctype/ctype_.c (_ctype_): Fix definition for 64 bit Cygwin.
	* libc/include/machine/setjmp.h: Change definition of _JBLEN to allow
	different values for 32 bit and 64 bit Cygwin.
	* libc/include/reent.h (stat64): Define as stat under Cygwin, instead
	of as __stat64.  Undef stat64 if not building Newlib.
