-   1. Copy-paste just the WFLAGS list items into `wflags-lax.txt`.  Keeping leading pounds and trailing backslashes is optional.

 5. Ensure that all tests pass, now under the reduced WFLGAS_OPT_LAX list.  Be deliberate about release mode and alternate architectures; i.e. that you aren't claiming to have fixed a test that always worked in x64-debug, but failed on a different configuration.  (Note that the overnight build will still catch that.)

+(*) This test was found later, upon fixing a problem in these instructions, so the original commit does not show it as fixed, like it does for the others.
