If that change worked for you, it means in particular that your platform
does not have <sys/select.h>. This should fix it:


2010-12-24  Bruno Haible  <address@hidden>

        sys_select: Ensure all necessary types on NonStop Kernel.
        * lib/sys_select.in.h: If the system does not have <sys/select.h>,
        include <sys/time.h>.
        * doc/posix-headers/sys_select.texi: Mention that it's missing on
        NonStop Kernel.
        Reported by Joachim Schmitz <address@hidden>.

 This header file is not self-contained on some platforms: it requires
