#1904: undefined reference to

     Type:  Bugs          |      Status:  new            
Milestone:  Boost 1.35.1  |   Component:  program_options
  Version:  Boost 1.35.0  |    Severity:  Problem        
 Keywords:                |  
--------------------------+-------------------------------------------------
 If one uses the boost_program_options, one gets a linker error:
 undefined reference to
 `boost::program_options::options_description::m_default_line_length'

 Cause:
 boost/program_options/options_description.hpp, line 158

 Currently:
         static const unsigned m_default_line_length;

 Should be:
         static const unsigned m_default_line_length = 80;

 The constant without assigneed value seems to become optimized out by the
 compiler.
