import core.stdc.math;

void main()
{
    lrintf(0.5);
}

> Error 42: Symbol Undefined _lrintf

Same also with -m64 and using the VC linker.

I know std.math has an lrint function which we can use, but it's strange the
above would fail to link. If 'lrintf' is a Posix-only function then its
prototypes should not be visible on Windows.
