You are correct - the module is not needed on cygwin (cygwin apps should
neither link against -lws2_32, nor call WSA*, when using POSIX socket
functions). The m4 file is correct:
checking whether <sys/socket.h> is self-contained... yes
checking if we need to call WSAStartup in winsock2.h and -lws2_32... no
However, the test file is incorrect:
gcc -g -O2 -o test-sockets.exe test-sockets.o ../gllib/libgnu.a
test-sockets.o: In function `main':
/home/eblake/gnulib/testdir2736/build/gltests/../../gltests/test-sockets.c:29:
undefined reference to `_gl_sockets_startup'
/home/eblake/gnulib/testdir2736/build/gltests/../../gltests/test-sockets.c:36:
undefined reference to `_gl_sockets_cleanup'
collect2: ld returned 1 exit status
Were you intending that all apps using sockets call
gl_sockets_{start,clean}up (in which case, you need to declare them,
perhaps as a no-op define, for non-mingw platforms), or were you intending
these functions to be called under the hood when using a socket-based API
in compliance with POSIX (in which case, your test should not call them
directly, but call a function that uses them under the hood)?

Don't work too hard, make some time for fun as well!
