Comment:

 There are 2 problems with the above patch on Windows:

 * the test fails, because `-ldl` can not be found.
 * in ghci, I can type `:set -lsomethingnonexistent` and it doesn't
 complain

 Note that running `ghci -lsomethingnonexistent` does fail on all
 platforms. Running `:set -lsomethingnonexist` in ghci on linux also fails.
