Licensing of .DLL files

Hello,

We'd like to distribute the following .DLL files within our software so
as our users don't have to install these files separately:
comerr32.dll, krb5_32.dll, libeay32.dll, libintl-2.dll, libiconv-2.dll
and ssleay32.dll.

However, the problem is that we don't know who we shall contact to get
the permission or learn about the conditions for distribution.

We know about BSD license to the libpq.dll file, however does it include
also the above mentioned libraries? Are the above mentioned files
covered by the PostgreSQL copyright as well?

Could you please advise? Any tips will be greatly appreciated.

Thanks very much.

Kind regards,

Vladimira Nitrova
