I am not aware of any problems such as the ones you describe.

I do however not understand what your bind version has to do with how curl is
built. curl does not use bind, the gethostbyname_r() curl uses is found in

How many arguments did the configure script detect that your
gethostbyname_r() uses? How many *does* it actually use (for real)?

This looks as if you didn't run configure on your Linux but have re-used the
lib/config.h that was generated on a different platform (Solaris, IRIX or
something). hostip.c:597 is code for those platforms.
