#54361: libopenraw @0.1.2_0 fails to build on 10.6 (and all platforms < 10.7, no
doubt) due to missing strnlen function

     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:
 Keywords:  snowleopard  |       Port:  libopenraw
-------------------------+------------------------
 Common problem:
 {{{
 ./ifdentry.hpp:118:30: error: use of undeclared identifier 'strnlen'
     s.assign((const char*)b, strnlen((const char*)b, len));
                              ^
 }}}
 There are different ways to fix it. I used my `snowleopardfixes` port
 <https://github.com/kencu/snowleopardfixes> as it takes 10 seconds to fix
 that way, and with this, the build succeeds.
 {{{
 $ port -v installed libopenraw
 The following ports are currently installed:
   libopenraw @0.1.0_1+gnome platform='darwin 10' archs='x86_64'
 date='2017-01-10T19:16:04-0800'
   libopenraw @0.1.2_0+gnome (active) platform='darwin 10' archs='x86_64'
 date='2017-06-21T10:38:21-0700'
 }}}

 You could also patch in the missing function to the files that need it.

 Of course, the proper fix would be for upstream to test for it and include
 it if needed, if they are interested in that.
