Patch: Better integration with GAMIN.

[Ira Cooper]

This is a minor change to make GAMIN more efficient when used with samba.

I couldn't find another #define to use other than the header guard.  I
consider it ugly, but I couldn't find another way to conditionalize
code.

If you have questions, please feel free to ask.

Thanks,

-Ira
