    If people think this is a good idea, I could start changing those  
    macros that use eassert (XSET, XCONS, XVECTOR, ...) to have GCC and  
    non-GCC versions, with the GCC versions using statement expressions  
    (inline functions wouldn't preserve the file and line number) and  
    temporary variables, and error out if ENABLE_CHECKING is defined but  
    GCC isn't used.  Should be straightforward, about a dozen places or  
    so to change I think.

Is this really necessary now?  I hope not.
