It would be a very Bad Idea (tm) for GCC to flag those cases, since
they are widely used to shut up compiler warnings about variables
which the compiler things are used before they are initialized.
(Compilers can err about this because they don't understand what
range of values can certain variables have, and thus don't know what
conditions could fire under what circumstances.)
