[Gnash] Warnings under g++ version 4

[Erik de Castro Lopo]

Hi all,

I running Ubuntu breezy on my main development machine and it has
g++ version 4.0.2 as its default compiler. However when I compile
gnash with this compiler I get rather a large number of warnings.

With C++ I usually find that warnings are well worth getting rid
of. Would a patch that removes these warnings be accepted?

The other thing I would also like to do is add a --enable-gcc-werror
option for the configure script. This would not be enabled by default,
but when it is enabled would add a -Werror to the CXXFLAGS to turn
all warnings into errors.

Finally, it might be nice for developers if the autgen.sh script
automatically configures with --enable-gcc-werror when the code
is pulled out of CVS.

I haven't jumped in and done this yet as I'd like to get feedback
from the other developers. All feedback (good, bad or indifferent) 
appreciated :-).

Cheers,
Erik
