This file is a placeholder to fool make.  The way that automake
and GNU make work together causes some files to depend on this
header, even if we're not building with Berkeley DB.

Obviously, if this file *is* used, it'll break and hopefully we can find
out why this file was generated by ${top_srcdir}/configure instead of
the real db.h.

If you run into some problems because of this file, please use mysql_bug
to generate a bug report, and give the exact output of make and any
details you can think of.  Send the message to bugs@lists.mysql.com.

Thank you!
