You can unlock the package, redefine the function and go. However, note
that the compiler will still generate code that calls the original C
function. It is a better practice normally to use a package with shadowing
symbols: it does not have this problem and its consequences, unlike symbol
redefinitions, are not undefined as per the ANSI Standard.
