Subject: * configure: Added feature tests for makedev, link/symlink/readlink,
 mkdir and mknod.

* eval.c (eval_init): Wrap #ifdefs around the registrations of
the wrappers for these functions.

* stream.c (mkdir_wrap): Wrap in #ifdef HAVE_MKDIR, and
provide a Windows version if HAVE_MKDIR is missing, but
HAVE_WINDOWS_H is true.
(makedev_wrap, major_wrap, minor_wrap): Wrap with #if HAVE_MAKEDEV.
(mknod): Use #if HAVE_MKNOD.
(symlink_wrap, link_wrap, readlink_wrap): Wrap with #if HAVE_SYMLINK.
