    I got the following messages from the v4.2b compiler. Does anyone know
    what
    it mean?
    
    /SWITCH=WNT_FIBER_TLS not used - is it misspelled?
    (This warning can be suppressed with -switch no_unused_swidmp)
    
    
    
    Thanks,
    Phung

|     Fiber support is not available in the VC++ 4.2 compiler.
    
    /d2"switch WNT_FIBER_TLS" is a backdoor way to enable fibers and TLS
    in the V5 compiler (perhaps one of the Beta versions).
    
    The intended interface for V5.0 is to use the /GT switch, but as
    discussed in 493.*, there is a driver problem so that /GT doesn't
    work with V5.0. I followed the suggestion in 493.4 and found that
    the following command line worked:
    
    	cl /d2"GT 0"
    
    Note that you *do* need the space between GT and 0
