I was fooling around with clang and noticed that it complains about
the "int x = x" construct under -Wall. That is IMHO a deficiency in
clang, since the idiom has a well-defined use in silencing
-Wuninitialized warnings.
IMO, that's a myth. The construct invokes undefined behavior at least
since C99, and the compilers are right to complain about it.
And I complained about this a couple months ago, as the compiler on
HP-NonStop stumbles across this too (by emitting a warning)
