--- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I think originally, the warning was supposed to catch things like
switch (n && MASK) {}
or even using the wrong variable in the switch(). Of course, it could be
smarter and avoid warning about the specific case 'switch(bool) {case true:
case false:}', which is what Linus says here:
https://lkml.org/lkml/2015/5/27/933
If only GCC had 1/100th of the developers of the Linux kernel...
The manual and the warning text could also say explicitly the reason for
warning (something like "often indicates a typo")
