The standard and portable way to override the allocator is at the point you instance C++ templates by specifing Allocator parameter. If, however, you want to globally change the default allocator without touching all your source files, the only way is to make modification on c++allocator.h, which is, in my opinion, never permitted by the standard and banned by god.
