/* I don't recommend using this interface in general. Use `free'.
*
* I'm told Microsoft Windows may use one set of `malloc' and `free'
* in a library, and another incompatible set in a statically compiled
* application that link to the library, thus creating problems if the
* application would invoke `free' on a pointer pointing to memory
* allocated by the library. This motivated adding this function.
*
* The theory of isolating all memory allocations and de-allocations
* within a code package (library) sounds good, to simplify hunting
* down memory allocation related problems, but I'm not sure if it is
* worth enough to motivate recommending this interface over calling
* `free' directly, though.
*
* See the manual section 'Memory handling under Windows' for more
* information.
