I have just compiled it on Windows32 and tried it.

The compilation using the given bat has failed to link:

But I have built the DScanner successfully using the old "bud" 
tool.

I have seen that this basic usage is not supported:
dscanner -s *.d

I have seen it doesn't support source code with unicode 
identifiers or chars.

How do you enable/disable specific tests when you use -s?

This code gives four problems to Dscanner:

void main() {
     auto x = float(5);
     auto r = 1. + 2;
     int items[5];
     import std.stdio;
     int.max.writeln;
}


In about 25_000 CLOC lines of my code DScanner has found several 
usages of the old-style alias syntax, that I will fix. Plus it 
has found three usages of the implicit string concatenation, and 
two of them are (the same) bug! Andrei Alexandrescu was very 
wrong to think that implicit string concatenation is a speck of 
dust. I am not going to close down that enhancement request.
