+ *
+ *  Version 0.1.12
+ *
+ *  The ANSI C standard committee, for the C99 standard, specified the
+ *  inclusion of a new standard include file called stdint.h.  This is
+ *  a very useful and long desired include file which contains several
+ *  very precise definitions for integer scalar types that is
+ *  critically important for making portable several classes of
+ *  applications including cryptography, hashing, variable length
+ *  integer libraries and so on.  But for most developers its likely
+ *  useful just for programming sanity.
+ *
+ *  The problem is that most compiler vendors have decided not to
+ *  implement the C99 standard, and the next C++ language standard
+ *  (which has a lot more mindshare these days) will be a long time in
+ *  coming and its unknown whether or not it will include stdint.h or
+ *  how much adoption it will have.  Either way, it will be a long time
+ *  before all compilers come with a stdint.h and it also does nothing
+ *  for the extremely large number of compilers available today which
+ *  do not include this file, or anything comparable to it.
+ *
+ *  So that's what this file is all about.  Its an attempt to build a
+ *  single universal include file that works on as many platforms as
+ *  possible to deliver what stdint.h is supposed to.  A few things
+ *  that should be noted about this file:
+ *
+ *    1) It is not guaranteed to be portable and/or present an identical
+ *       interface on all platforms.  The extreme variability of the
+ *       ANSI C standard makes this an impossibility right from the
+ *       very get go. Its really only meant to be useful for the vast
+ *       majority of platforms that possess the capability of
+ *       implementing usefully and precisely defined, standard sized
+ *       integer scalars.  Systems which are not intrinsically 2s
+ *       complement may produce invalid constants.
+ *
+ *    2) There is an unavoidable use of non-reserved symbols.
+ *
+ *    3) Other standard include files are invoked.
+ *
+ *    4) This file may come in conflict with future platforms that do
+ *       include stdint.h.  The hope is that one or the other can be
+ *       used with no real difference.
+ *
+ *    5) In the current verison, if your platform can't represent
+ *       int32_t, int16_t and int8_t, it just dumps out with a compiler
+ *       error.
+ *
+ *    6) 64 bit integers may or may not be defined.  Test for their
+ *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
+ *       Note that this is different from the C99 specification which
+ *       requires the existence of 64 bit support in the compiler.  If
+ *       this is not defined for your platform, yet it is capable of
+ *       dealing with 64 bits then it is because this file has not yet
+ *       been extended to cover all of your system's capabilities.
+ *
+ *    7) (u)intptr_t may or may not be defined.  Test for its presence
+ *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
+ *       for your platform, then it is because this file has not yet
+ *       been extended to cover all of your system's capabilities, not
+ *       because its optional.
+ *
+ *    8) The following might not been defined even if your platform is
+ *       capable of defining it:
+ *
+ *       WCHAR_MIN
+ *       WCHAR_MAX
+ *       (u)int64_t
+ *       PTRDIFF_MIN
+ *       PTRDIFF_MAX
+ *       (u)intptr_t
+ *
+ *    9) The following have not been defined:
+ *
+ *       WINT_MIN
+ *       WINT_MAX
+ *
+ *   10) The criteria for defining (u)int_least(*)_t isn't clear,
+ *       except for systems which don't have a type that precisely
+ *       defined 8, 16, or 32 bit types (which this include file does
+ *       not support anyways). Default definitions have been given.
+ *
+ *   11) The criteria for defining (u)int_fast(*)_t isn't something I
+ *       would trust to any particular compiler vendor or the ANSI C
+ *       committee.  It is well known that "compatible systems" are
+ *       commonly created that have very different performance
+ *       characteristics from the systems they are compatible with,
+ *       especially those whose vendors make both the compiler and the
+ *       system.  Default definitions have been given, but its strongly
+ *       recommended that users never use these definitions for any
+ *       reason (they do *NOT* deliver any serious guarantee of
+ *       improved performance -- not in this file, nor any vendor's
+ *       stdint.h).
+ *
+ *   12) The following macros:
+ *
+ *       PRINTF_INTMAX_MODIFIER
+ *       PRINTF_INT64_MODIFIER
+ *       PRINTF_INT32_MODIFIER
+ *       PRINTF_INT16_MODIFIER
+ *       PRINTF_LEAST64_MODIFIER
+ *       PRINTF_LEAST32_MODIFIER
+ *       PRINTF_LEAST16_MODIFIER
+ *       PRINTF_INTPTR_MODIFIER
+ *
+ *       are strings which have been defined as the modifiers required
+ *       for the "d", "u" and "x" printf formats to correctly output
+ *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
+ *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
+ *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
+ *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
+ *       defined if INT64_MAX is not defined.  These are an extension
+ *       beyond what C99 specifies must be in stdint.h.
+ *
+ *       In addition, the following macros are defined:
+ *
+ *       PRINTF_INTMAX_HEX_WIDTH
+ *       PRINTF_INT64_HEX_WIDTH
+ *       PRINTF_INT32_HEX_WIDTH
+ *       PRINTF_INT16_HEX_WIDTH
+ *       PRINTF_INT8_HEX_WIDTH
+ *       PRINTF_INTMAX_DEC_WIDTH
+ *       PRINTF_INT64_DEC_WIDTH
+ *       PRINTF_INT32_DEC_WIDTH
+ *       PRINTF_INT16_DEC_WIDTH
+ *       PRINTF_INT8_DEC_WIDTH
+ *
+ *       Which specifies the maximum number of characters required to
+ *       print the number of that type in either hexadecimal or decimal.
+ *       These are an extension beyond what C99 specifies must be in
+ *       stdint.h.
+ *
+ *  Compilers tested (all with 0 warnings at their highest respective
+ *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
+ *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
+ *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
+ *
+ *  This file should be considered a work in progress.  Suggestions for
+ *  improvements, especially those which increase coverage are strongly
+ *  encouraged.
