0034  *  Version 0.1.15.4
0035  *
0036  *  The ANSI C standard committee, for the C99 standard, specified the
0037  *  inclusion of a new standard include file called stdint.h.  This is
0038  *  a very useful and long desired include file which contains several
0039  *  very precise definitions for integer scalar types that is
0040  *  critically important for making portable several classes of
0041  *  applications including cryptography, hashing, variable length
0042  *  integer libraries and so on.  But for most developers its likely
0043  *  useful just for programming sanity.
0044  *
0045  *  The problem is that some compiler vendors chose to ignore the C99
0046  *  standard and some older compilers have no opportunity to be updated.
0047  *  Because of this situation, simply including stdint.h in your code
0048  *  makes it unportable.
0049  *
0050  *  So that's what this file is all about.  Its an attempt to build a
0051  *  single universal include file that works on as many platforms as
0052  *  possible to deliver what stdint.h is supposed to.  Even compilers
0053  *  that already come with stdint.h can use this file instead without
0054  *  any loss of functionality.  A few things that should be noted about
0055  *  this file:
0056  *
0057  *    1) It is not guaranteed to be portable and/or present an identical
0058  *       interface on all platforms.  The extreme variability of the
0059  *       ANSI C standard makes this an impossibility right from the
0060  *       very get go. Its really only meant to be useful for the vast
0061  *       majority of platforms that possess the capability of
0062  *       implementing usefully and precisely defined, standard sized
0063  *       integer scalars.  Systems which are not intrinsically 2s
0064  *       complement may produce invalid constants.
0065  *
0066  *    2) There is an unavoidable use of non-reserved symbols.
0067  *
0068  *    3) Other standard include files are invoked.
0069  *
0070  *    4) This file may come in conflict with future platforms that do
0071  *       include stdint.h.  The hope is that one or the other can be
0072  *       used with no real difference.
0073  *
0074  *    5) In the current version, if your platform can't represent
0075  *       int32_t, int16_t and int8_t, it just dumps out with a compiler
0076  *       error.
0077  *
0078  *    6) 64 bit integers may or may not be defined.  Test for their
0079  *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
0080  *       Note that this is different from the C99 specification which
0081  *       requires the existence of 64 bit support in the compiler.  If
0082  *       this is not defined for your platform, yet it is capable of
0083  *       dealing with 64 bits then it is because this file has not yet
0084  *       been extended to cover all of your system's capabilities.
0085  *
0086  *    7) (u)intptr_t may or may not be defined.  Test for its presence
0087  *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
0088  *       for your platform, then it is because this file has not yet
0089  *       been extended to cover all of your system's capabilities, not
0090  *       because its optional.
0091  *
0092  *    8) The following might not been defined even if your platform is
0093  *       capable of defining it:
0094  *
0095  *       WCHAR_MIN
0096  *       WCHAR_MAX
0097  *       (u)int64_t
0098  *       PTRDIFF_MIN
0099  *       PTRDIFF_MAX
0100  *       (u)intptr_t
0101  *
0102  *    9) The following have not been defined:
0103  *
0104  *       WINT_MIN
0105  *       WINT_MAX
0106  *
0107  *   10) The criteria for defining (u)int_least(*)_t isn't clear,
0108  *       except for systems which don't have a type that precisely
0109  *       defined 8, 16, or 32 bit types (which this include file does
0110  *       not support anyways). Default definitions have been given.
0111  *
0112  *   11) The criteria for defining (u)int_fast(*)_t isn't something I
0113  *       would trust to any particular compiler vendor or the ANSI C
0114  *       committee.  It is well known that "compatible systems" are
0115  *       commonly created that have very different performance
0116  *       characteristics from the systems they are compatible with,
0117  *       especially those whose vendors make both the compiler and the
0118  *       system.  Default definitions have been given, but its strongly
0119  *       recommended that users never use these definitions for any
0120  *       reason (they do *NOT* deliver any serious guarantee of
0121  *       improved performance -- not in this file, nor any vendor's
0122  *       stdint.h).
0123  *
0124  *   12) The following macros:
0125  *
0126  *       PRINTF_INTMAX_MODIFIER
0127  *       PRINTF_INT64_MODIFIER
0128  *       PRINTF_INT32_MODIFIER
0129  *       PRINTF_INT16_MODIFIER
0130  *       PRINTF_LEAST64_MODIFIER
0131  *       PRINTF_LEAST32_MODIFIER
0132  *       PRINTF_LEAST16_MODIFIER
0133  *       PRINTF_INTPTR_MODIFIER
0134  *
0135  *       are strings which have been defined as the modifiers required
0136  *       for the "d", "u" and "x" printf formats to correctly output
0137  *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
0138  *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
0139  *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
0140  *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
0141  *       defined if INT64_MAX is not defined.  These are an extension
0142  *       beyond what C99 specifies must be in stdint.h.
0143  *
0144  *       In addition, the following macros are defined:
0145  *
0146  *       PRINTF_INTMAX_HEX_WIDTH
0147  *       PRINTF_INT64_HEX_WIDTH
0148  *       PRINTF_INT32_HEX_WIDTH
0149  *       PRINTF_INT16_HEX_WIDTH
0150  *       PRINTF_INT8_HEX_WIDTH
0151  *       PRINTF_INTMAX_DEC_WIDTH
0152  *       PRINTF_INT64_DEC_WIDTH
0153  *       PRINTF_INT32_DEC_WIDTH
0154  *       PRINTF_INT16_DEC_WIDTH
0155  *       PRINTF_UINT8_DEC_WIDTH
0156  *       PRINTF_UINTMAX_DEC_WIDTH
0157  *       PRINTF_UINT64_DEC_WIDTH
0158  *       PRINTF_UINT32_DEC_WIDTH
0159  *       PRINTF_UINT16_DEC_WIDTH
0160  *       PRINTF_UINT8_DEC_WIDTH
0161  *
0162  *       Which specifies the maximum number of characters required to
0163  *       print the number of that type in either hexadecimal or decimal.
0164  *       These are an extension beyond what C99 specifies must be in
0165  *       stdint.h.
0166  *
0167  *  Compilers tested (all with 0 warnings at their highest respective
0168  *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
0169  *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
0170  *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
0171  *
0172  *  This file should be considered a work in progress.  Suggestions for
0173  *  improvements, especially those which increase coverage are strongly
0174  *  encouraged.
