+Crosscompiling
+--------------
+
+ To compile correctly collectd needs to be able to initialize static
+ variables to NAN (Not A Number). Some C libraries, especially the GNU
+ libc, have a problem with that.
+
+ Luckily, with GCC it's possible to work around that problem: One can define
+ NAN as being (0.0 / 0.0) and `isnan' as `f != f'. However, to test this
+ ``implementation'' the configure script needs to compile and run a short
+ test program. Obviously running a test program when doing a cross-
+ compilation is, well, challenging.
+
+ If you run into this problem, you can use the `--with-nan-emulation'
+ configure option to force the use of this implementation. We can't promise
+ that the compiled binary actually behaves as it should, but since NANs
+ are likely never passed to the libm you have a good chance to be lucky.
