* File: dfi.h
* Purpose: HDF internal header file
* Invokes: stdio.h, sys/file.h
* Contents:
* Compilation parameters
* Machine-dependent definitions
* Flexibility definitions: i/o buffering, dynamic memory, structure i/o
* Size parameters
* Remarks: To port to a new system, only dfi.h and Makefile need be modified.
* This file is included with user programs, but users do not see it.
