Mmmm... well now this options should run on:
- Mac OS X
- Digital Unix
- Sun Solaris
- *BSD
- Linux (of course...)
- win32 (VC, MingW)
(well, all platform tested, I think... I don't know it it works on VMS)
In this case it seem that our FreeTDS do not detect that netdb library
is reentrant...
You can add a NETDB_REENTRANT define to config.h 

>From configure.in

AC_CANONICAL_HOST
netdb_reentrant=no
case $host in
  *-*-osf*)
    CPPFLAGS="$CPPFLAGS -D_OSF_SOURCE -D_XOPEN_SOURCE_EXTENDED
-D_POSIX_C_SOURCE=199506L"
    netdb_reentrant=yes
    ;;
  *-*-hpux11*)
    CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE_EXTENDED"
    netdb_reentrant=yes
    ;;
esac

So we should just add cygwin case...
