HAVE_SOCKETS is defined unconditionally in s/ms-w32.h, yet some w32*.c
files use HAVE_SOCKETS #ifdefs.

It would be good to get rid of those. 

Only msdos does not define HAVE_SOCKETS currently, and a lot of the
HAVE_SOCKETS #ifdefs are only used when subprocesses is defined.  That
means that most of those can simply go away.
