I actually use it occasionally to verify that any rw_assert() calls I add will
display correctly in verbose mode, but that isn't really the point.

The definition of verbose is 'to use more words than are necessary'. Typically
verbose mode for a program enables additional output but it doesn't change the
behavior of the program in other ways.

Just because we don't use the option frequently isn't a good reason misuse it.
At home we don't use our fine china dinnerware more than once a year, but I
wouldn't dare use the gravy boat as an oil pan.

Oh, I agree. They make it difficult to not notice a failure.

Well, now I have two more problems with this change. First it disables the
window for CRT errors only. It should probably do the same for the gpfault
error box. Second, it sends the messages only to the debugger output window. It
should probably send them to stderr...

If you are running the tests from the MSVC IDE the normal popup shouldn't
appear. The MSVC debugger should be catching these types of failures and
If you're launching an individual test from the IDE with F5 or CTRL+F5 you
would already have to specify the --compat command line option somewhere. If
you are using the runtests project, it should get the --compat flag
automatically from the runall.wsh script. So you would need to find a way to
disable the command line option then.
