State-Changed-From-To: open->closed
State-Changed-By: bajo
State-Changed-When: Tue May  6 10:18:14 2003
State-Changed-Why:
    Reconfirmed on 2.95 -> 3.3, but it's fixed in 3.4 CVS 20030503 probably thanks to the new parser. The error
    message is:
    
    pr10639.cpp:21: error: return type specification for constructor invalid
    
    Thanks for your report.
