I knew that would work for cygwin, but wasn't sure it would work for 
mingw.  In that case, this portion of the earlier patch:

could be replaced with the attached version, instead (note: attached 
file is NOT a complete patch, and hasn't been tested extensively.)  The 
newer version has the benefit that it avoids the race introduced by the 
above.  I'm not sure it is advisable to change the definition of 
$wrapper itself for cygwin/mingw host, though, so I introduced a new 
variable wrapperdot.
