+This implementation module for gc_c++.h provides an implementation of
+the global operators "new" and "delete" that calls the Boehm
+allocator.  All objects allocated by this implementation will be
+non-collectable but part of the root set of the collector.
+
+You should ensure (using implementation-dependent techniques) that the
+linker finds this module before the library that defines the default
+built-in "new" and "delete".
