I want to interoperate with existing C libraries that expect a
pointer.  High performance computing requires this (at least for
now).  My point is not that there is anything wrong with libstdc++.
For high performance we need a different vector-like container that
does interoperate with C.

Are there any other STL-compatible containers that have the required
properties?
