    1.11 + * This file provides a really simple implementation of the system-
    1.12 + * dependent portion of the JPEG memory manager.  This implementation
    1.13 + * assumes that no backing-store files are needed: all required space
    1.14 + * can be obtained from malloc().
    1.15 + * This is very portable in the sense that it'll compile on almost anything,
    1.16 + * but you'd better have lots of main memory (or virtual memory) if you want
    1.17 + * to process big images.
    1.18 + * Note that the max_memory_to_use option is ignored by this implementation.
