thanks for input guys, but for some reason I don't get same warnings as you:
$ g++-4.6 -Wall -Wextra lzo_gcc_test.cpp -llzo2
lzo_gcc_test.cpp:27:5: warning: unused parameter âargcâ [-Wunused-parameter]
lzo_gcc_test.cpp:27:5: warning: unused parameter âargvâ [-Wunused-parameter]
$ g++-4.6 -v
Using built-in specs.
