 /* Get definition of 'sigset_t'.
    But avoid namespace pollution on glibc systems and "unknown type
    name" problems on Cygwin.
+   On OS/2 kLIBC, sigset_t is defined in <sys/select.h>, too. In addition,
+   if <sys/param.h> is included, <types.h> -> <sys/types.h> -> <sys/select.h>
+   are included. Then <signal.h> -> <pthread.h> are included by GNULIB. By the
+   way, <pthread.h> requires PAGE_SIZE defined in <sys/param.h>. However,
+   <sys/param.h> has not been processed, yet. As a result, 'PAGE_SIZE'
+   undeclared error occurs in <pthread.h>.
    Do this after the include_next (for the sake of OpenBSD 5.0) but before
    the split double-inclusion guard (for the sake of Solaris).  */
