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".
