/*************************************************************************

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

uncollectible 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".
