Subject:	[PATCH] Make libio.h work in cygwin-b20

libio.h does not work when #included in cygwin-b20.

This is because of this code therefrom:

: #ifndef __P
: # if _G_HAVE_SYS_CDEFS
: #  include <sys/cdefs.h>
: # else
: #  ifdef __STDC__
: #   define __P(p) p
: #  else
: #   define __P(p) ()
: #  endif
: # endif
: #endif /*!__P*/

[and, further down, code that uses __P, like

: extern int _IO_getc __P ((_IO_FILE *__fp));

]

This code is OK; the GNU C Library has included a definition of __P in
<sys/cdefs.h> for donkey's years (since before the changelog began, it
seems).

But cygwin-b20's <cdefs.h> does not contain such a definition, so that
any code that includes <libio.h> before including anything else that
defines __P breaks.

This patch adds such a definition to <sys/cdefs.h>. (The path in the
patch may well be wrong.)

+#else

 #endif

I hope this is useful.
