*
* Borland seems to have a problem in DOS mode for exactly 64K.
* It gives you a segment with an offset of 8 (perhaps to store its

* detect and deal with it. This code should not be needed in
* Windows or OS/2 modes, and only in 16 bit mode. This code has
* been updated by Alexander Lehmann for version 0.89 to waste less
* memory.
*
* Note that we can't use png_size_t for the "size" declaration,
* since on some systems a png_size_t is a 16-bit quantity, and as a
* result, we would be truncating potentially larger memory requests
* (which should cause a fatal error) and introducing major problems.
