The question is where this line comes from and where it is going to.
It sounds like an informative message. Does it come from Gambas directly
or from hunspell, i.e. does it appear when you run your program but
replace every call to hunspell with a dummy line? And how are you using
hunspell, as a library or are you calling the external program?
The lines appears to be sent to stderr, right?

I'm going to assume that it doesn't come from Gambas. Then, if you use
the library, that's very undesirable behaviour and you should talk to
the hunspell people. If you use the external hunspell program, does it
have a switch to turn these informatives off? If not, but the message
arrives on stderr instead of stdout, you can capture and throw away
stderr in your Gambas program to prevent the message from coming through.

Tobi
