This looked weird enough that I looked into it as well. I found the culprit
to be the <sys/select.h> override in gnulib. This file is being included
from the system's <sys/types.h> and <sys/time.h> and itself includes
<sys/types.h> and <sys/time.h>, leading to some half-included files. I'm
applying this fix. Thanks for the report!

Well, this time, gnulib was at fault.

        Fix compilation error on OSF/1 4.0.
        * lib/sys_select.in.h: When invoked from OSF/1 <sys/types.h> or
        <sys/time.h>, simply delegate to the system header.
