sys_select on mingw

[Bruno Haible]

On mingw, I'm seeing this compilation error:

$ make test-sys_select-c++.o
depbase=`echo test-sys_select-c++.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        g++-3 -mno-cygwin -DHAVE_CONFIG_H -I. -I..  -DGNULIB_STRICT_CHECKING=1 
-DIN_GNULIB_TESTS=1 -I. -I. -I.. -I./.. -I../gllib -I./../gllib 
-I/usr/local/mingw/include -Wall   -MT test-sys_select-c++.o -MD -MP -MF 
$depbase.Tpo -c -o test-sys_select-c++.o test-sys_select-c++.cc &&\
        mv -f $depbase.Tpo $depbase.Po
In file included from test-sys_select-c++.cc:22:
../gllib/sys/select.h:451: error: `close' was not declared in this scope
test-sys_select-c++.cc:34: warning: 'signature_check35' defined but not used
make: *** [test-sys_select-c++.o] Error 1

Apparently it was introduced on 2011-07-06.


This fixes it.
