+# According to doc/fftw3.pdf, the configure script should choose the best value
+# for $CFLAGS.  We will assume that the script knows what it is doing.
+#
+# By default we will leave out these machine-dependent optimizations.  If your
+# machine supports these, feel free to add them to the configure options.
+# Note that fftw may refuse to compile by doing so -- watch for error messages
+# about the precision not matching.
+# --enable-fma      enable optimizations for machines with fused multiply-add
+# --enable-k7       enable AMD K7 optimizations, including 3dNow!
+# --enable-sse      enable SSE optimizations (Pentium III+)
+# --enable-sse2     enable SSE2 optimizations (Pentium IV+)
+# --enable-altivec  enable Altivec optimizations (PowerPC G4+)
+# --enable-portable-binary
+#                   disable compiler optimizations that would produce
+#                   unportable binaries
+#
+# You can also build fftw using a different precision.  --enable-float may be
+# required depending on any SIMD code enabled with the above options.
+# --enable-single       compile fftw in single precision
+# --enable-float        synonym for --enable-single
+# --enable-long-double  compile fftw in long-double precision
+#
+# Heinz Wiesinger points out that these extra precisions can be compiled 
+# as well.  --enable-float will append an 'f' to the library names, while
+# --enable-long-double will append an 'l'.  We have to compile three separate
+# times instead of once to create all of the files.
+#
+# Note that the ./configure; make; make install commands below are not inside
+# a loop.  You may be able to --enable one of the SIMD options for one
+# precision, but not another.  (This should be documented somewhere...)
