I think I'd appreciate that warning when writing portable code:
The warning can be useful if the 1 is replaced with a macro
which may or may not expand to 1, or an enum defined in an #ifdef,
or an implementation-dependent expression like ((char)-1 < 0).
But of course, it depends on how many false positives the warning
tends to give for normal programs.
Maybe there could be a warning option to turn on and off some
warnings that do not apply with the particular #defines and
constants being used. (And also turn on/off -Wunreachable
for this case.)
