underscore not matched

           Product: Regexp
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW

/* Example code is always best for reporting bugs. I could have made it a bit
 * more easy, but I'm tired (sorry). The Sun 1.4.0_01-b03 SDK I have run this
 * on seems to disagree with jakarta's regexp; I am inclined to believe Sun is
 * right...
