The error is not spurious and is correct, it doesn't matter if you use it
afterwards or not.
ISO C++98 in [stmt.dcl]/3 says:
"It is possible to transfer into a block, but not in a way that bypasses
declarations with initialization. A program that jumps 77) from a point where a
local variable with automatic storage duration is not in scope to a
point where it is in scope is ill-formed unless the variable has POD type (3.9)
and is declared without an initializer (8.5)."
And your testcase violates this, thus is ill-formed and the compiler diagnoses
it.
