Hi everybody,

A few questions:

1) What is the performance gain (if any) by moving john on linux-x86-mmx 
to linux-64-x86-mmx  for Intel processors?

2) Why does the CYGWIN and DJGPP versions do not calculate virtual c/s 
in the benchmark, and in general how does John calculate virtual c/s?

3) If we will need to migrate a version of John to MS Visual C++, which 
version should be the easiest to do?

Thanks, Ami.
