+6.5 update:
+I disabled incremental GC on Darwin in this version, since I couldn't
+get gctest to pass when the GC was built as a dynamic library. Building
+with -DMPROTECT_VDB (and threads) on the command line should get you
+back to the old state. - HB
+
+./configure --enable-cplusplus results in a "make check" failure, probably
+because the ::delete override ends up in a separate dl, and Darwin dynamic
+loader semantics appear to be such that this is not really visible to the
+main program, unlike on ELF systems. Someone who understands dynamic
+loading needs to lookat this. For now, gc_cpp.o needs to be linked
+statically, if needed. - HB
