Maybe the thing to do is to create a separate file with the fixed 
routine in make it available as a drop in that people can download but 
not as part of the standard mapserver release which would just call the 
broken gd function. This should avoid licensing issues wrt mapserver.

If someone needs the drop in fix then they can grab it and make part of 
their mapserver build. This also means that when the fix is released in 
gd mapserver just keeps on working with/without the drop in fix.

It's a little more work, but makes the integration much easier because 
you don't have to install a patched gd in a production environment and 
worry about security updates to it, etc. Just a thought.
