Michel Boaventura reported the following link errors trying to
compile GNU PSPP on mingw:

> gl/.libs/libgl.a(close.o):close.c:(.text+0x2d): undefined reference to
> address@hidden'
> gl/.libs/libgl.a(close.o):close.c:(.text+0x45): undefined reference to

> gl/.libs/libgl.a(close.o):close.c:(.text+0x5f): undefined reference to

It looks like the gnulib close module needs to recommend linking
against the ws2_32 library on Windows.  Or perhaps it should add
it directly to LIBS, since the "close" function is so basic that
it seems odd to have to add to LDADD to be able to use it.

I think that the former can be implemented like this:

diff --git a/m4/close.m4 b/m4/close.m4
