0049  *     ANSI C requires that the type before the ellipsis be a

0051  *     or double) and because we defined pseudo-tags that are
0052  *     outside the range of legal Aldus-assigned tags.
0053  * NB: tsize_t is signed and not unsigned because some functions
0054  *     return -1.
0055  * NB: toff_t is not off_t for many reasons; TIFFs max out at
0056  *     32-bit file offsets, and BigTIFF maxes out at 64-bit
0057  *     offsets being the most important, and to ensure use of
