It is defined this way to placate the compiler when HAVE_LIBGEOTIFF is  
not defined.  Are you attempting to build libLAS using libgeotiff and/ 
or GDAL?  What do the options in your nmake.opt look like in regards  
to these two libraries?  If you have them installed, but they are not  
defined correctly in nmake.opt, you might see this sort of error.
