Thorsten, the biggest problem I have found with libraries that offer this 
optimization, and I am glad that VC++ 7.1's is one of them, is that the 
definition of "short" is non-configurable, except by changing a very 
important header file. Even if a change to that header file is made, there 
is no guarantee that the compiler actually reads the header file and does 
not have its contents hardcoded when an include directive for that header 
file is seen in source code, since the header file is a "standard" (i.e. 
included with the compiler) header file.

For example, in VC++, IIRC, it is set to somewhere in the neighborhood of 
15. I would much rather that they upped this value to 31 or 63, or somewhere 
thereabouts.
