Thanks for the reply and sorry for the insufficient information.

I used gnulib-tool to import files.

$ cd "D:\usr\Tatsu\mingw32work\gnulib\socket_poll"
#(Here is working directory, #the clone directory is ../gnulib)

$ ../gnulib/gnulib-tool --import sys_socket poll

You may need to add #include directives for the following .h files.
  #include <poll.h>
  #include <sys/socket.h>

You may need to use the following Makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
  $(LIBSOCKET)
  $(LIB_POLL)
  $(LIB_SELECT)

Don't forget to
  - add "lib/Makefile" to AC_CONFIG_FILES in ./configure.ac,
  - mention "lib" in SUBDIRS in Makefile.am,
  - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am,
  - mention "m4/gnulib-cache.m4" in EXTRA_DIST in Makefile.am,
  - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC,
  - invoke gl_INIT in ./configure.ac.


#**********************

I have modified the files according the above instruction.
One point set 'SUBDIRS = lib' gave an automake error.

I saw  
http://www.gnu.org/software/gnulib/manual/html_node/Invoking-gnulib_002dtool.html

But I found :

First, you must ensure Autoconf can find the macro definitions in 
gnulib-comp.m4. Use the ACLOCAL_AMFLAGS specifier in your top-level Makefile.am 
file, as in:

     ACLOCAL_AMFLAGS = -I m4

I wrote it not in the top level so that I move it in the top level in the 
lib/Makefile.am.

And execute,

aclocal
autoconf
automake --add-missing

However, gl_EARLY and gl_INIT are not recognized.

Any suggestions?
