Sorry, I'm not familiar with those.

> configure: WARNING: netdb.h: present but cannot be compiled

What happens when you merely try to compile this file, without any
special options for the compiler?

  #include <netdb.h>
  typedef int dummy;

If this doesn't compile, then to fix it what include files need to be
included before <netdb.h>, and why?  If it _does_ compile, then why is
tar/configure getting a different result than this little test
program?
