Mateusz,

I am ambivalent about this.  Even though /GX was replaced, latter  
versions of the compiler respect it, correct?  The problem with  
MSVC_VER is the ease at which someone can forget to specify it as part  
of the compilation.  I don't like this particular approach of GDAL and  
MapServer.  It's too easy to forget.  If we had lots of switches that  
were version dependent, I could see a stronger need for it, but I  
don't think we should do it for a single switch that is indefinitely  
supported throughout the MSVC compiler chain.
