<pre>Compiling with clang-cl there is excessive output being produced every time a
macro is encountered. There must be a way developed to turn off all this
output, which is neither a warning or an error. Nobody is going to want to look
through all this output by default. Please either turn this output off by
default ( preferred ) or create a compiler switch to do so.
The output looks like:
