 38 * This file is force-included in hunspell code.  Its purpose is to add memory
 39 * reporting to hunspell without modifying its code, in order to ease future
 40 * upgrades.
 41 *
 42 * This file is force-included through mozilla-config.h which is generated
 43 * during the configure step.
 44 *
 45 * Currently, the memory allocated using operator new/new[] is not being
 46 * tracked, but that's OK, since almost all of the memory used by Hunspell is
 47 * allocated using C memory allocation functions.
