Try converting the real to a float first:

printf("%f\n", cast(float) cos(0.883573));

I had trouble linking when using cos in gdc
my solution was to use version and  cosl
cos worked fine for me in dmd.exe

import std.c.math;
import std.math;
version(Windows) {
return std.math.cos(x);
}else {
return cast(VALUE)std.c.math.cosl(cast(real)x);
}
