Code defines static variables in header which is bad form.
static const boost::system::error_category& system_category = boost::asio::error::get_system_category();
In gcc the warning could be disabled with -Wno-unused-variable, but that disables valuable warnings.
It might be a good idea then to file a bug report with GCC requesting that the two warnings be separated.
If you really need to define global variables in a header only library, you can define static members of a template class. It's a fancy trick (not sure if it has a name). Perhaps there are portablity issues with it.
I'm sure there are plenty of creative ways to obfuscate your code. Ideas, anyone? :) Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
