digitalmars.D - tiger crypto algorithm

I decided to give 'tiger' a crack, basically because the name is kewl.

Sadly I am stuck. My code does not produce the correct output, and neither 
does the sample code I downloaded from here:

http://www.cs.technion.ac.il/~biham/Reports/Tiger/

Can anyone get the sample code to produce the correct output?
I want to use it to debug my code.

I tried the sameples on windows, using MSVC 6.0. The 64bit version 
produces different output to the 32bit version and neither produce the 
correct output.

I managed to get the 64bit version to compile by redefining the typedef to 
__in64 which is a Microsoft 64bit int type and removing all the LL's from 
the constant hex values.

Perhaps it compiles on linux? I don't have a linux box here at home, so 
I'll have to try it at work tomorrow.

Duh! Cancel that, I have figured it out. The code was never intended to 
work on windows, it has...

/* Big endian:                                         */
#if !(defined(__alpha)||defined(__i386__)||defined(__vax__))
#define BIG_ENDIAN
#endif

Changing it to...

/* Big endian:                                         */
#if 
!(defined(__alpha)||defined(__i386__)||defined(__vax__)||defined(WIN32))
#define BIG_ENDIAN
#endif

Causes the correct behaviour and output.

FYI.. in addition to the big/little endian fix below you have to define..

//typedef unsigned long long int word64;
typedef unsigned __int64 word64;

to get the 64bit version to work.
