//  Revision History
//   31 Oct 01  use BOOST_HAS_LONG_LONG to check for "long long" (Jens M.)
//   16 Apr 01  check LONGLONG_MAX when looking for "long long" (Jens Maurer)
//   23 Jan 01  prefer "long" over "int" for int32_t and intmax_t (Jens Maurer)
//   12 Nov 00  Merged <boost/stdint.h> (Jens Maurer)
//   23 Sep 00  Added INTXX_C macro support (John Maddock).
//   22 Sep 00  Better 64-bit support (John Maddock)
//   29 Jun 00  Reimplement to avoid including stdint.h within namespace boost
//    8 Aug 99  Initial version (Beman Dawes)

Mr. Shah is a reclusive C++/C# developer lurking somewhere in the depths of the city of London. He learnt physics at Kings' College London and obtained a Master in Science there. Having earned an MCAD, he teeters on the brink of transitioning from C++ to C#, unsure of which language to jump to. Fortunately, he also knows how to use .NET interop to merge code between the two languages (which means he won't have to make the choice anytime soon).
 
His interests (apart from programming) are walking, football (the real one!), philosophy, history, retro-gaming, strategy gaming, and any good game in general.
 
He maintains a website / blog / FAQ / junk at shexec32.serveftp.net, where he places the best answers he's written to the questions you've asked. If you can find him, maybe you can hire Mr. Shah to help you with anything C++[/CLI]/C#/.NET related Smile | :) .
