+     test suite.  We cannot get too many people working on this.  It is
+     not difficult to write a test, find a definition of the function
+     which I normally can provide, if necessary, and start writing tests
+     to test for compliance.  Beside this, take a look at the sources
+     and write tests which in total test as many paths of execution as

+[14] We need to write a library for on-the-fly transformation of streams

+     This is needed in several places in the GNU libc and I already have
+     rather concrete plans but so far no possibility to start this.
+
+
+[15] Cleaning up the header files.  Ideally, each header style should
+     follow the "good examples".  Each variable and function should have
+     a short description of the function and its parameters.  The prototypes
+     should always contain variable names which can help to identify their
+     meaning; better than
+
+               int foo __P ((int, int, int, int));
