Please correct me if I'm wrong here but, the script/process called by the
AGI could
be any executable adhering to the AGI standard.  This could be a compiled C
or any
language executable that simply parses the startup info provided by the AGI
and
communicates with * via stdin and stdout.  This means that the executable
would be
standalone and not need to be linked to the GPL code.  I think this means
that the
source of any AGI application would not be subject to the GPL licensing if
the author
would so choose.
