I've investigated a bit. Later snapshots have the
line
h_errno DATA
in winsup.din, whereas 19990115 snapshot has
h_errno
I don't know what this means, but I'm guessing it has
something to do with why it seems to link with the old
snapshot but not the newer ones.
Although the program seems to work for me, I haven't
tested it enough to tell if the part of the code that
uses h_errno is broken (i.e. links but doesn't work)
or not.
Apparently Glenn's patch solves the problem, but I'm
wondering if this is a case like many old programs
declaring
int errno
when they should use
#include <errno.h>
In other words, perhaps the code should just
#include <netdb.h>
(Note that the last few lines above are off-topic for
Cygwin)
