+   for compiling the shared-library code.  In this case, we'll #define
+   FFTW_DLL to add dllexport attributes to the specified functions in
+   fftw3.h.
+
+   If we don't specify dllexport explicitly, then libtool
+   automatically exports all symbols.  However, if we specify
+   dllexport explicitly for any functions, then libtool apparently
+   doesn't do any automatic exporting.  (Not documented, grrr, but
+   this is the observed behavior with libtool 1.5.8.)  Thus, using
+   this forces us to correctly dllexport every exported symbol, or
+   linking bench.exe will fail.  This has the advantage of forcing
+   us to mark things correctly, which is necessary for other compilers
+   (such as MS VC++). */
