sys_socket: inconsistent linker warnings?

[Simon Josefsson]

Linking gsasl on mingw fails with:

gsasl.o: In function `readln':
/home/jas/src/gsasl/gsasl-0.2.29/src/gsasl.c:101: undefined reference to 
`_recv_used_without_requesting_gnulib_module_recv'
gsasl.o: In function `main':
/home/jas/src/gsasl/gsasl-0.2.29/src/gsasl.c:480: undefined reference to 
`_rpl_connect'

The linker failures are understandable, I haven't added these gnulib
modules (yet).

But why does it complain about '_rpl_connect' rather than
'socket_used_without_requesting_gnulib_module_connect'?

Looking at sys_socket.in.h, I'd expect that the failures would be
similar for all socket functions, and that they follow the longer form.
