 * @brief 各初期データ用ヘッダ構造体 / Template file header information (see "init.c").  16 bytes.
 * @details
 * Note that the sizes of many of the "arrays" are between 32768 and
 * 65535, and so we must use "unsigned" values to hold the "sizes" of
 * these arrays below.  Normally, I try to avoid using unsigned values,
 * since they can cause all sorts of bizarre problems, but I have no
 * choice here, at least, until the "race" array is split into "normal"
 * and "unique" monsters, which may or may not actually help.
 *
 * Note that, on some machines, for example, the Macintosh, the standard
 * "read()" and "write()" functions cannot handle more than 32767 bytes
 * at one time, so we need replacement functions, see "util.c" for details.
 *
 * Note that, on some machines, for example, the Macintosh, the standard
 * "malloc()" function cannot handle more than 32767 bytes at one time,
 * but we may assume that the "ralloc()" function can handle up to 65535
 * butes at one time.  We should not, however, assume that the "ralloc()"
 * function can handle more than 65536 bytes at a time, since this might
 * result in segmentation problems on certain older machines, and in fact,
 * we should not assume that it can handle exactly 65536 bytes at a time,
 * since the internal functions may use an unsigned short to specify size.
 *
 * In general, these problems occur only on machines (such as most personal
 * computers) which use 2 byte "int" values, and which use "int" for the
 * arguments to the relevent functions.
