commit 4268ec187d401b9b132afa1a13c73e0026a53c5d

    Recognize _ in attribute names
    
    Ada attribute names can contain "_", but the lexer currently does not
    allow this -- even though the "attributes" array lists some attributes
    spelled this way.
    
    This patch fixes the bug and adds test cases for the existing
    attributes.
    
    This was reviewed off-list by Joel.  I'm checking it in.
