+  Likewise, collectd needs to know the layout of doubles in memory, in order
+  to craft uniform network packets over different architectures. For this, it
+  needs to know how to convert doubles into the memory layout used by x86. The
+  configure script tries to figure this out by compiling and running a few
+  small test programs. This is of course not possible when cross-compiling.
+  You can use the `--with-fp-layout' option to tell the configure script which
+  conversion method to assume. Valid arguments are:
+
+    * `nothing'    (12345678 -> 12345678)
+    * `endianflip' (12345678 -> 87654321)
+    * `intswap'    (12345678 -> 56781234)
