*
* Version 0.1.10
*
* 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.
*
* Acknowledgements
*
* The following people have made significant contributions to the
* development and testing of this file:

* Chris Howie
* John Steele Scott
