  13 This implementation module for gc_c++.h provides an implementation of
  14 the global operators "new" and "delete" that calls the Boehm
  15 allocator.  All objects allocated by this implementation will be
  16 non-collectable but part of the root set of the collector.
  17
  18 You should ensure (using implementation-dependent techniques) that the
  19 linker finds this module before the library that defines the default
  20 built-in "new" and "delete".
