/*
 * alloc.h
 *
 * Memory management functions. Because most of these functions are
 * actually declared in stdlib.h I have decided to simply include that
 * header file. This file is included by malloc.h. My head hurts...
 *
 * NOTE: In the version of the Standard C++ Library from Cygnus there
 * is also an alloc.h which needs to be on your include path. Most of
 * the time I think the most sensible option would be to get rid of
 * this file.
 *
 * This file is part of the Mingw32 package.
