He meant C++ compilers.  But the situation in D is somewhat different 
because of garbage collection.  malloc is itself a memory allocator and 
D's GC is also an allocator, so having D's allocator call malloc would 
be like one retail store buying all their products from another retail 
store in bulk--it's much more efficient just to order from the 
distributer :-)
