// The NuttX C library an be build in two modes: (1) as a standard, C-libary
// that can be used by normal, user-space applications, or (2) as a special,
// kernel-mode C-library only used within the OS.  If NuttX is not being
// built as separated kernel- and user-space modules, then only the first
// mode is supported.
