    cmd/cgo: don't ignore qualifiers, don't cast to void* · fb8c896a
    Ian Lance Taylor authored
    The cgo tool used to simply ignore C type qualifiers. To avoid problems
    when a C function expected a qualifier that was not present, cgo emitted
    a cast to void* around all pointer arguments. Unfortunately, that broke
    code that contains both a function declaration and a macro, when the
    macro required the argument to have the right type. To fix this problem,
    don't ignore qualifiers. They are easy enough to handle for the limited
    set of cases that matter for cgo, in which we don't care about array or
    function types.
    
    Fixes #17537.
