Comment:

 Ok, I see the same problem. It's a bug in the code that the clang compiler
 treats as an error. We should fix the code, since the developers won't
 since they seem to have abandoned this software long ago (the last release
 was 20 years ago). Until we fix the code, I would like to blacklist clang,
 except that this port is not UsingTheRightCompiler and therefore does not
 respect the blacklist.
