#12918: Spirit:extra template parameters in mini_c sample
--------------------------------+-------------------------------
 Reporter:  lisi <942748117@…>  |       Type:  Bugs
   Status:  new                 |  Milestone:  To Be Determined
Component:  None                |    Version:  Boost 1.63.0
 Severity:  Problem             |   Keywords:  mini_c parameters
--------------------------------+-------------------------------
 as the following code shows,[[BR]]
 '''boost_1_63_0\boost\utility\result_of.hpp'''
 {{{
                   .
                   .
                   .
 template<typename F, typename FArgs>
 struct result_of_nested_result : F::template result<FArgs>
 {};
                   .
                   .
                   .
 }}}
 struct '''result''' only needs one template parameter.But in the next two
 files in mini_c sample,  '''result''' is provided more template
 parameters. Because of this, the code can't ran successfully.

 '''I write "/* */" behind the code need to be removed'''
