The main problem is it would not come even close to compiling on any of
my compilers (non-MSVC if you remember).  I never intended to bug you to
make the source perfectly ANSI compliant, since it was your code in the
first place and the only reason to make it portable would be public
release.

I'd be more than happy to try again if you want to send it to me...  The
new version from Nalimov is being worked on.  There are problems compiling
his code with gcc as well, as his code actually crashes GCC (he uses lots
of C++ templates which seems to break it.)

But if you have time, and are interested, let me know.  We can make this
work for unix as well...
