+It is not portable to use "std{in,out}" as "lvalues" (for instance,
+building under Sun Solaris breaks here). The portable solution is to use
+freopen(3). Unfortunately, to achieve the same effect than fdopen(3) on
+"std{in,out}", one has to use "/dev/std{in,out}" (which in turn is not
+really portable, but at least more portable than using "std{in,out}"
+as "lvalues"). The only "we know it better" alternative would be to
+just replace the code with a fflush(3) on the streams and know that the
+stream has not recognized the changed underlying filedescriptor. But
+this again is not really portable, although also working for mostly all
+Unix platforms.
