DESCRIPTION
  This header file contains general types and macros that are of use
  to all modules.  The values or definitions are dependent on the specified
  target.  T_WINNT specifies Windows NT based targets, otherwise the 
  default is for ARM targets.

       T_WINNT  Software is hosted on an NT platforn, triggers macro and
                type definitions, unlike definition above which triggers
                actual OS calls

This section contains comments describing changes made to this file.
Notice that changes are listed in reverse chronological order.

when       who     what, where, why
--------   ---     ----------------------------------------------------------
01/27/16    rl     (c_lewisr) fix logic issues with int's
06/11/01    gr     Added MOD_BY_POWER_OF_TWO macro.
04/12/01    sq     Added inpdw and outpdw macros
           vas     Added solaris support
04/06/01    gr     Removed the definitions of abs and labs.
01/25/01   day     Merged from MSM5105_COMMON.00.00.05.
					 Added include for stdlib.h within WINNT ifdef
					 Added support for ARM_ASM
					 Added support SWIG preprocessor.
09/09/99   tac     Merged in a bunch of panther changes.
08/11/99   jct     Corrected conditional compilation around labs to check for
                   labs instead of abs
06/30/99   jct     Added PC_EMULATOR capability for INTLOCK and INTLOCKSAV
06/15/99   jct     Cleanup to make work in Windows NT environment.  Addition
                   of int(n) types where n is 8,16,32,64 and addition of
                   unit64.  Removal of OS comments and defines as this is replaced
                   by T_WINNT.  Conditional inclusion of MAX, MIN, labs, abs,
                   NULL definitions.  Removal of volatile from packed definition
                   stdlib.h included for Win32 based targets since this replaces several
                   of the define here.  Changed out uts calls to be comet calls.
                   Added a defines for Windows NT targets to define away symbols
                   no longer supported
04/09/99    ms     Lint cleanup.

11/20/98    ms     Typecast to volatile pointers in inp,outp,inpw and outpw.
10/10/98   jct     Honing of OS and T_ definitions, added T_WINNT as a target
                   which triggers something different then which OS since
                   we may be running REX on an NT platform, but strictly 
                   speaking, the application software is using REX, not NT
                   as the OS.  Changed ROM for WINNT/ARM targets to be nothing
                   instead of const 
09/09/98   jct     Updates to merge ARM support with 186 support, added some
                   new type aliases, added some segmented architecture macros,
                   updated comments, removed unused code, updated declaration
                   of inp/outp to have cdecl 
08/01/98   jct     Updates to support ARM processor
03/25/96   jah     Moved SET_VECT to 80186.h

06/11/93   jah     Changed FPOS() to cast the pointer to 'near' to avoid the
                   compiler complaints about lost segments.
01/28/93   twp     Added ARR_SIZE macro to return number of array elements.
07/17/92   jah     Changed int1 from 'char' to 'signed char'

MACRO INTLOCK / INTFREE

DESCRIPTION
  INTLOCK Saves current interrupt state on stack then disables interrupts.
  Used in conjunction with INTFREE.

  INTFREE Restores previous interrupt state from stack.  Used in conjunction
  with INTLOCK.

PARAMETERS
  None

DEPENDENCIES
  The stack level when INTFREE is called must be as it was just after INTLOCK
  was called.  The Microsoft C compiler does not always pop the stack after a
  subroutine call, but instead waits to do a 'big' pop after several calls.
  This causes these macros to fail.  Do not place subroutine calls between
  these macros.  Use INTLOCK/FREE_SAV in those cases.

DESCRIPTION
  Convert a character to uppercase, the character does not have to

DESCRIPTION
  These character attribute macros are similar to the standard 'C' macros

  by Microsoft 'C'.

PARAMETERS
  c             Character to be examined

DEPENDENCIES
  None

RETURN VALUE
  DECCHK        True if the character is a decimal digit, else False
  HEXCHK        True if the chacters is a hexidecimal digit, else False

SIDE EFFECTS
  None
