I think the real problem was a declaration in libguile/net_db.c in
guile 1.4:

/* Some systems do not declare this.  Some systems do declare it, as a
   macro.  */
#ifndef h_errno
extern int h_errno;
#endif

This fails with some versions of cygwin because h_errno is declared in
a DLL and needs extra magic to pull it in.  Removing those lines would
probably fix it.
