Even,

I have also seen that many of the free software distributions are not
including GPC support in AGG for obvious reasons.  So if we don't need this
function it would seem to be a bad one to check for.  I have taken the
liberty of creating a trac ticket for this issue.  I'd encourage you to
add yourself as a cc: for it.

I also created a new svn-trunk "version" in trac that we can use when
reporting bugs specifically in the current development trunk.

Best regards,
