#2 libagg 2.1 doesn't build with gcc 3.4.3
I get errors when building with gcc 3.4.3:

When I build it exactly the same way, with version
3.2.3, I get no such errors. Even enabling the
-fpermissive option doesn't work, as it just runs into
more errors, later on. If no one has fixed these
problems, I imagine I could probably do it (assuming
it's likely you'll accept my patch).
One major difference between the two versions of gcc
is that the latter is much more strict about
standards-compliance. Therefore, I imagine these
problems aren't fundamentally specific to GCC.

Oops, I wasn't using the "updated" version of 2.1.
I would just point out that a normal, 3-level version
numbering system would have avoided this confusion. The
typical practice is to have Major.Minor.Patch. Patch gets
incremented when the only changes made are fixes. Minor
gets incremented when backward-compatible, new
functionality is added (and Patch is then reset to 0). Major
gets incremented (and Minor & Patch reset) when
non-backward compatible changes are made.
