Raw Message
On mingw (and similarly MSVC), I'm getting this link error:

i686-w64-mingw32-gcc -g -O2 -L/usr/local/mingw32/lib -o test-poll.exe test-poll.o libtests.a ../gllib/libgnu.a libtests.a -lws2_32 -lws2_32
../gllib/libgnu.a(poll.o): In function `windows_compute_revents_socket':
../../gllib/poll.c:250: undefined reference to `recv_used_without_requesting_gnulib_module_recv'

This fixes it:
