This does not match with my experience.  I do not have CLASSPATH set.
In my cygwin directory I only have:

\usr\share\gettext\Libintl.jar      
\usr\share\java\Libgcj-3.2.jar   

The only other jar files on my machine are in the JRE.  I would
hope that a standalone executable would not want to use them.
Just in case I tried renaming rt.jar.   Sure enough java Hello
no longer works but recompiling and running ./Hello.exe still 
Results in a stackdump.  

The version of gcj I'm using is:

C:\BruceA\java>gcj --version
gcj (GCC) 3.2 20020818 (prerelease)
