I would like to know (in more details than gnat documentation) the critical=
ity of these warnings options:=20
 ** "-gnatwd" (Implicit dereferencing)
 ** "-gnatwf" (Unreferenced formals)
 ** "-gnatwh" (Hiding)
 ** "-gnatwm" (Modified but unreferenced variables)
 ** "-gnatwk" (Variables that could be constants)

I mean, for instance, a code with several variables that could be constants=
, even in local procedures is an ugly code, not clean, but generally it's o=
k if works. But I just want to understand what kind of other complications =
that code could get due to not fixing these type of constructs. Someone onc=
e told me that it could bring out code vulnerabilities, the binary app coul=
d become "hackeable", but he gave not a deep explanation (so I cannot convi=
nce others about this). And I did not find in ARM05 and gnat documentation.=
 So, could someone give me a hint?

Regards.
