(probably) restore buildability on Cygwin

Only probably because I don't have easy direct access to a Cygwin build
environment yet; sadly, it doesn't install under Wine.  I have inspected
the output of gcc -dM -E foo.h for different compiler/OS combinations,
though, and this should now be right.

\draw[thick] (-2.5,-0.2) rectangle (2.5,0.2);
\draw plot[domain=-2.4:2.4,samples=250] (\x, {0.15*sin(9.2*\x r)});
