Comment (by dersh@…):

 I was trying to build something else (openmodelica) and ran into the same
 problem

 {{{
 :info:build
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/pthread.h:423:66:
 error: expected ';' after top level declarator
 }}}

 So, is this actually a bug in XCode 8?
