well if the intent is cleaning adding a package mask is just more burden,
not less.
If they compile fine with the latest stable gcc better leave them unmasked,

do you have any pointers or keyword to search?
Because once upon a time there were incompatible changes frequently (2.95
=> 3.x with x < 4 was bloody) but nowadays everything "C" seem more stable.
