/*************************************************************************
|

|
|
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".
