13476	Linker error when using Spirit Classic	janis.ruksans@…	Joel de Guzman	"After upgrading to Boost 1.60, my project using Spirit Classic no longer builds, failing with a linker error complaining about undefined references to boost::system::generic_category() and boost::system::system_category().

The minimal test case is:

{{{
#include <boost/spirit/include/classic.hpp>

int
main (int argc, char ** argv)
{
   return 0;
}
}}}

which gives results in the following compiler output:

{{{
$ g++ -Wall test.cxx
/tmp/ccpjbwj6.o: In function `__static_initialization_and_destruction_0(int, int)':
test.cxx:(.text+0x23f): undefined reference to `boost::system::generic_category()'
test.cxx:(.text+0x249): undefined reference to `boost::system::generic_category()'
test.cxx:(.text+0x253): undefined reference to `boost::system::system_category()'
