Ok (when regression tested).  Did you run the gcc regression testsuite on it?  To install it, we'd need a testsuite run on it.  Roughy, run the testsuite before your patch, save off the .sum file, run it after your patch, then run contrib/compare_tests before.sum after.sum and see if there is any output.  You might need expect/tcl/dejagnu installed to do that.



If you want to contribute longer term (larger patches), you'll want to get started on your paper work, if you've not done that already.  And, welcome.  Before you say, but...  let me say, what took so long, 10 years is a long while?  :-)
