Hi Tom,

I finally was able to build this after messing around with my paths
even more.

The attached testcase hangs on my machine on Linux with gcj, but
works with Sun Java. Would you be able to try this out on your end?
Once this works on Linux, I can move on to the Windows piece.
I would offer to troubleshoot this on Linux, but I'm really short on
time lately :(

1. Compile Test.java to Test.exe
2. Add the directory with Test.exe to your path.
3. Altenatively compile ProcessBuilderTest.java to a classfile
  and run with Sun Java (it works), or else compile ProcessBuilderTest.java
  to an executable with gcj, then try running the executable (it hangs).
