Comment (by kencu):

 So stumbled across a few more ports where this occurs. So far the common
 thread is c++ code that includes <assert.h> I think.

 No clang compiler worked when I tried it tonight on libde265, which showed
 the error. But building with gcc7 worked (i386).

 So I guess that's why not on PPC (we don't use clang on PPC).

 Running the legacy-support test suite on Leopard i386 with clang-7.0 works
 fine, including realpath replacement.

 It only seems to be c++ code that includes <assert.h> where things get
 sticky.

 <assert.h> is a bit weird -- it can be included multiple times. Whether
 that should matter I do not know, at present.
