Licensing question about mysql_com.h

[James Ots]

I am writing a MySQL connector for the Dart programming language. I
was hoping to licence it under the BSD Licence, but since it uses
modified parts of mysql_com.h, which is licensed under the GPL, I'm
guessing that I'll have to licence my connector under the GPL as well?
And therefore, anyone who used the connector would also have to
licence their software under the GPL too?

Am I correct about this? I looked at the FOSS exception, but it
doesn't seem to apply in this case.
