Thanks.
What is a difference between library libmysqlclient for cygwin and libraries
mysqlclient and libmySQL distributing with MySQL database. Linker found
all external references. Previously I created own classes and DLL libraries
that could be loaded dynamically from ROOT. It was a fine property
of ROOT. Why it is necessary to rebuild ROOT now?

You should get a MySql client library for Windows (libmysqlclient)
and then rebuild ROOT on Windows. You can find such a lib for
the cygwin environment (but this requires them cygwin.dll to run
ROOT with mysql).

Cheers, Fons.
