     Type:  defect                        |     Status:  new
 Priority:  Normal                        |  Milestone:
Component:  ports                         |    Version:  2.4.2
 Keywords:  py36-matplotlib Snow Leopard  |       Port:  py36-matplotlib
------------------------------------------+-----------------------------
 In order to compile py36-matplotlib on Snow Leopard I had to modify line
 1313 of file _macosx.m from this

 {{{
     for (size_t state_index = 0; state_index < n; state_index++)
 }}}

 to this

 {{{
     size_t state_index;
     for (state_index = 0; state_index < n; state_index++)
 }}}

 I think this solution should work on any other system, but better leave
 the decision to the experts...

 I didn't check if the same issue exists for other py?? versions
