Hi,

Thanks, but that's not the issue. I could create a patch or use sed, if
I knew the right way to package this.

The main question is wether it is better to include that header
(originally not belonging to another program) in the google C++ APIs
package (since no other package needs that file) or to create an extra
package like mongoose3 with that file only (since that would be the
right way - it is an header from another program).
