sys_select, sys_time: port 2013-01-30 Solaris 2.6 fix to Cygwin Problem reported by Marco Atzeri in <http://lists.gnu.org/archive/html/bug-gnulib/2013-03/msg00000.html>. * lib/sys_select.in.h [HAVE_SYS_SELECT_H && _CYGWIN_SYS_TIME_H]: Simply delegate to the system <sys/select.h> in this case too. Also, pay attention to _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TIME_H only if OSF/1, since otherwise Cygwin breaks, and it doesn't seem to be needed on Solaris either. * lib/sys_time.in.h [_CYGWIN_SYS_TIME_H]: Simply delgate to the system <sys/time.h> in this case.

@node func
@section func

The @code{func} module makes sure that you can use the predefined
identifier @code{__func__} as defined by C99 in your code.

A small example is:

@smallexample
#include <config.h>
#include <stdio.h> /* for printf */

int main (void)
@{
    printf ("%s: hello world\n", __func__);
@}
@end smallexample

Note that @code{sizeof} cannot be applied to @code{__func__}: On SunPRO C
compiler, @code{sizeof __func__} evaluates to 0.
