Unfortunately AGG 2.5 is more the final 2.4 version. As mentioned
before on this list, various 2.4 versions exist and we need many new
features of AGG.

You need to interpret this as the 2.4 source version (the one you can
download now from the AGG website).

Agree. Maybe also point out that recent 2.4 version would do as well.

I try to solve all warnings but as you can see the warnings come from
the AGG header files. This does not necessarily exclude that the root
of the "problem" sits in the Gnash source since AGG is based on
templates. However, I solved all warnings could. There are some left,
like AGG mixing integers and enums. I got no response from Maxim (AGG
author) when talking about the problem.

At the other hand, the AGG renderer itself uses heavily templates so
that the compiler emits lots of identical warnings.

Anyway, you can safely ignore these warnings.

Since there apparently are some warnings for render_handler_agg*, I'll
have a closer look at it once I get the opportunity.
