create_source_map doesn't work per example on Windows

[blickly]

What steps will reproduce the problem?
1. Try to build a source map using the instructions from here:
http://code.google.com/closure/compiler/docs/inspector.html
Specifically:
$ java -jar compiler.jar --js example.js --create_source_map ./example-map 
--js_output_file example-compiled.js

What is the expected output? What do you see instead?
Expected: The compiler runs and the map is created.
Actual: FileNotFound exception:
java.io.FileNotFoundException: null\.\example-map (The system cannot find 
the path specified)

What version of the product are you using? On what operating system?
The compiler doesn't seem to support a --version parameter, nor is a 
version given in the --help output or the README file. This is one I 
downloaded (didn't build it locally), file date is 04/12/2009.
On Windows XP.

Please provide any additional information below.

This thread from a couple of weeks back explains the problem and gives a 
workaround; Joseph Schorr said he'd submit a fix on Nov 30th:

Thanks for creating an issue for this. Joseph's change was actually summitted until
12/7.  It will be in the next release.
