This variable is not really used.
Initialization in declaration. This mainly obfuscates the non-use of the
variable.
Rather the opposite is true:
void f(void)
{
int error = 0; // GCC warns that error is unused
}
void g(void)
{
int error;
error = 0; // GCC is silent
}
In this case it does not help, because error is used. But an assignment
halfway down the function definitely would not improve the situation.
