/* 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). */
