*
*  Version 2.7e, 14-Dec-97, Hughes STX.
*
*  Modification history:
*
*   V1.0  20-Jul-91, J Love     Original version (for CDF V2.1).
*   V2.0  17-May-92, J Love     IBM PC & HP-UX port.  CDF V2.2.
*   V2.1  15-Sep-92, J Love     CDF V2.3 (shareable/zVar/NeXT).
*   V2.2  30-Oct-92, J Love     Added variable values display to CDFinquire.
*   V2.3  25-Jan-94, J Love     CDF V2.4.
*   V2.3a  8-Feb-94, J Love     DEC Alpha/OpenVMS port.
*   V2.4  13-Dec-94, J Love     CDF V2.5.
*   V2.5  20-Jan-95, J Love     `Trailer' function prototype.
*   V2.5a 19-Jan-95, J Love     IRIX 6.0 (64-bit).
*   V2.5b 28-Feb-95, J Love     `IsGraphChr' function prototype.  Solaris 2.3
*                               IDL i/f.  Pass `char' as `int'.
*   V2.6   6-Apr-95, J Love     POSIX.
*   V2.6a 18-Apr-95, J Love     More POSIX.
*   V2.6b  9-May-95, J Love     Virtual memory under Microsoft C 7.00.  Added
*				`EPOCHdataType'.  EPOCH styles.
*   V2.6c 13-Jun-95, J Love	EPOCH custom format.  Linux.
*   V2.6d 25-Aug-95, J Love	More system include files for UNIX.  Moved
*				`ASSIGNnotNULL' from `cdflib.h'.  CDFexport-
*				related changes.  More virtual memory for
*				Microsoft C 7.00.
*   V2.7   9-Sep-96, J Love	CDF V2.6.
*   V2.7a 26-Nov-96, J Love	Better handling of HP-UX POSIX-compliant
*				compiler (c89).
*   V2.7b 21-Feb-97, J Love	Removed RICE.

*   V2.7d 16-Nov-97, J Love	More Windows NT.
*   V2.7e 14-Dec-97, J Love	Added ALPHAVMSi encoding.
*   V2.7f 27-May-98, M Liu 	SunOS/gnu has stdarg.h while SunOS/bsd doesn't.
*   V2.7g 07-Feb-01, M Liu      Added Solaris running on PC platform.
*   V2.8  02-May-01, M Liu      Added handling for CYGWIN.
*   V2.9  25-Nov-02, M Liu      Added handling for 64-bit Solaris sparcv9.
*   V2.10 08-Apr-04, M Liu      Added a new function for data type CDF_EPOCH16.
*   V2.11 11-Jul-05, M Liu      Added MingW port for PC.
*   V2.12 30-Jan-06, M Liu      Added FreeBSD port.
*   V2.13 09-Jun-06, M Liu      Added HP-UX and AIX for LFS.
*   V2.14 09-Jul-06, M Liu      Added MacOSX on i386 PC (macosXintel).
*   V2.15 18-Apr-08, M Liu      Further modified MacOS X into macosXppc and 
*                               maxosXintel. For PPC, pre-defined macro 
*                               "__ppc__" and "__ppc64__" by gcc for 32/64-
*                               bit mode, respectively on Mac.
*   V2.16 28-Apr-09, M Liu      Added linux-PPC (pre-defined macro "__PPC__"
*                               by gcc for either 32/64-bit).
*   V2.17 16-Jul-12, M Liu      Changed "uInt" to "uInt4", "uLong" to "uLongx"
*                               and "Byte" to "Byte1" so they won't be in
*                               conflict with the same typedef's defined in
*                               zlib.
*   V2.18 09-Aug-13, M Liu      Added cdfid_AllocateMemory, cdfid_getCDFid,
*                               cdfid_FreeMemory.
*   V2.19 09-Jan-18, M Liu      Added ARM and IA64 openVMS architectures
*                               support.
