Ok, I put in the new Cygwin1.dll from the latest 32bit developer snapshot:

$ uname -a
CYGWIN_NT-5.1 dimension 1.7.31s(0.272/5/3) 20140716 11:15:29 i686 Cygwin

Then, I removed /usr/lib/resolv.a, so the call is explicitly done on the new Cygwin
DLL.

I removed the complete source code from my /usr/local/src directory, re-extracted
the sendmail source, made and installed. So now the test-output of the sendmail rule
"check_mail" looks like this:

$ echo "check_mail daniel AT cygwin DOT com" | /usr/sbin/sendmail -d8.20 -bt
dns_getcanonname(dimension, trymx=1)

It works. As you can see, this is done on a WinXP machine. I could also test on a
Win7 machine. I don't have Win8 or Win8.1.

Greetings,
Daniel
