fpending: port to recent Cygwin change to stdio_ext.h Reported by LRN in <http://lists.gnu.org/archive/html/bug-gnulib/2013-08/msg00028.html>. * lib/fpending.h: Don't worry about HAVE_DECL___FPENDING; just declare __fpending unless it's a macro. A duplicate decl shouldn't hurt. * m4/fpending.m4 (gl_FUNC_FPENDING): Check that an __fpending call compiles and links, instead of separately checking for decl and lib function. * modules/fpending (configure-ac): Adjust to fpending.m4's renaming of shell variable.

Description:
Determine the number of bytes waiting in the output buffer of a stream.
