Is Java broken on the trunk?

[Mark Mitchell]

I get:

  ../../../libjava/java/lang/natObject.cc:506: ISO C++ forbids declaration of 
     `_Jv_ThreadId_t' with no type
  ../../../libjava/java/lang/natObject.cc:506: parse error before `;' token

when building libjava on the trunk.  Is this a known problem?

Thanks!
