#47824: tup 0.7.1: conflicting types for 'readlinkat'

 Reporter:  baldur.kristinsson@…  |      Owner:  macports-tickets@…
     Type:  defect                |     Status:  new
 Priority:  Normal                |  Milestone:
Component:  ports                 |    Version:  2.3.3
 Keywords:                        |       Port:  tup
----------------------------------+--------------------------------
 Tup 0.7.1 fails to install on OS X 10.10.3, Xcode version 6.3.2. It seems
 that readlinkat() is defined twice with slightly differing return types.

 Here are the relevant lines from the build log:
