/*
* History:
* pjt 31oct89 _trace_ added as defined() option, BUFALIGN 8.
* rjs 21feb90 Added alternate way of defining FORT_TRUE and FALSE
* to improve XMP and Cray-2 compatibility. This change
* care of Brian Glendenning.
* mjs ?? Increased BUFSIZE to avoid apparent OS problem on "ral".
* rjs 8feb91 Convex definitions.
* mjs 18mar91 More Convex definitions.
* rjs 16apr91 Removed macros redefining memcpy as bcopy -- no longer
* needed, and bcopy is slower on the Suns anyway.
* rjs 24jun91 Added memcmp define for the convex.
* rjs 18dec92 Added hpux. Various tidying.
* mjs 19feb93 Added mips.
* jm 07nov94 Added definition of Null and typedef of Void. The
* Void typedef permits proper casting in both ANSI
* and non-ANSI archs. Also added definition to permit
* the use of const in non-ANSI declarations.
* jm 17nov94 Changed the conditional definition around the typedef
* of Void because Sun defines __STDC__ even when it is
* zero! Defined PROTOTYPE as 1 if __STDC__ is set to 1;
* otherwise it is undefined. Also added ARGS definition
* to aide forward declartion prototyping.
* rjs 20nov94 Added "alpha" ifdef.
* rjs 19mar97 Add FORTRAN_LOGICAL define and check that miriad.h declarations
* have not been done before doing them again.
* pjt 14jun01 use WORDS_BIGENDIAN to figure out the pack routines
* removed 'trace' clutter from the old multiflow
* pjt 24jun01 PPC/powerpc is a BIGENDIAN (linux) machine
* pjt 21jun02 MIR4
* pjt 4jan05 merged in the new ATNF HAS_STRERROR

* Void is typedef'd to the proper word depending on the level of
