I get the same error with Mohan's GCJ 3.3 build. 

A little bit of investigation reveals that it happens in a call 
to java.net.URLStreamHandler.parseURL( ) within the 
java.net.URL(URL, String, URLStreamHandler) constructor. 
The VMClassLoader has only "file:.\" as the base URL for 
searching the file "build.properties". 
(Note that File.separator is "\" on Windows.)

With that information, this code in URLStreamHandler.parseURL( )
looks suspect:
----------------------------- 8< -------------------------------
else if (start < end)
  {
    // Context is available, but only override it if there is a new file.
    file = file.substring(0, file.lastIndexOf('/'))
            + '/' + spec.substring(start, end);
    ref = null;
  }
----------------------------- 8< -------------------------------

This seems to assume that '/' is the file separator and this
might explain why you see it on Windows but not Linux.
