Build broken with gcc-4.4.1 on Ubuntu 9.10

[Dong Tiger]

Hi,

When I tried to build ggl on Ubuntu 9.10. I got the following error.

workspace/ggl/google-gadgets-for-linux/ggadget/variant.cc: In destructor ‘ggadget::Variant::~Variant()’:

workspace/ggl/google-gadgets-for-linux/ggadget/variant.cc:68: error: dereferencing type-punned pointer will break strict-aliasing rules

make[2]: *** [ggadget/CMakeFiles/ggadget-1.0.dir/variant.o] Error 1

Any idea to fix that?
