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.)

I hope this is useful.

Looks like this has already been fixed. winsup/include/sys/cdefs.h:
#ifndef _SYS_CDEFS_H
#define _SYS_CDEFS_H
#ifdef __cplusplus
#define __BEGIN_DECLS extern "C" {
#define __END_DECLS }
#else
#define __BEGIN_DECLS
#define __END_DECLS
#endif
#define __P(protos) protos /* full-blown ANSI C */
#endif
