Title: Add note to `%cython` Black-Scholes example warning of missing erf.

As @kluono pointed out in #2588, the example might not compile on Windows
due to a missing `erf` symbol. Since I do not have a Windows box to test any
potential fixes, the best I can do is include a note warning the user that
the example might not compile.
