 # Enable a whole bunch of warnings, but turn off:
-# - implicit fallthrough because that does not recognize some cases where it's desired (and I *really* want this one!)
 # - comment because we use a bunch of those, and they're not really all that harmful.
 # - address, because that occurs for our mkostemp check (weak-linking requires us to compare `&mkostemp == nullptr`).
-# - strict-aliasing, because on old GCCs (*Travis*) those are triggered by maybe.h, so you get it every time it is included.
-# - redundant-move, because we have one that is required on old libc
