This statement is not true, and the key to solve the warnings.  It seems that I
was not the only one who did not understand the cdefs.h problem.

./telnetd/des.c:#include <sys/cdefs.h>

In particular:

./libcsupport/include/sys/statvfs.h:#include <sys/cdefs.h>

This causes the warning (e.g. included from <rtems/confdefs.h>).
