Permission is hereby granted to copy this code for any purpose,
provided the above notices are retained on all copies.

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".
