/**
 * This file is force-included in hunspell code.  Its purpose is to add memory
 * reporting to hunspell without modifying its code, in order to ease future
 * upgrades.
 *
 * This file is force-included through mozilla-config.h which is generated
 * during the configure step.
 *
 * Currently, the memory allocated using operator new/new[] is not being
 * tracked, but that's OK, since almost all of the memory used by Hunspell is
 * allocated using C memory allocation functions.
