    With all due respect to the person who raised the question: a link failure is 
    NOT any indication that such buffer overflows are present.  It is an 
    indication of a toolchain that creates implicit dependencies and broke linking 
    of many shared libraries and dynamically loadable modules other than BLCR.
    
    Neal, have you or anyone else tried removing -fno-stack-protector to see if 
    things work correctly on Fedora 9 or 10?  Its possible they might.
    
    If somebody can point to the proper way to resolve the linkage problem, 
    without also breaking things for platforms w/o stack-protector support in gcc, 
    then I'd be happy to apply the fix.
