-/* This header file provides the reentrancy.  */
-
-/* The reentrant system calls here serve two purposes:
-
-   1) Provide reentrant versions of the system calls the ANSI C library
-      requires.
-   2) Provide these system calls in a namespace clean way.
-
-   It is intended that *all* system calls that the ANSI C library needs
-   be declared here.  It documents them all in one place.  All library access
-   to the system is via some form of these functions.
-
-   There are three ways a target may provide the needed syscalls.
-
-   1) Define the reentrant versions of the syscalls directly.
-      (eg: _open_r, _close_r, etc.).  Please keep the namespace clean.
-      When you do this, set "syscall_dir" to "syscalls" in configure.in,
-      and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
-
-   2) Define namespace clean versions of the system calls by prefixing
-      them with '_' (eg: _open, _close, etc.).  Technically, there won't be
-      true reentrancy at the syscall level, but the library will be namespace
-      clean.
-      When you do this, set "syscall_dir" to "syscalls" in configure.in.
-
-   3) Define or otherwise provide the regular versions of the syscalls
-      (eg: open, close, etc.).  The library won't be reentrant nor namespace
-      clean, but at least it will work.
-      When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
-      configure.in.
-
-   Stubs of the reentrant versions of the syscalls exist in the libc/reent
-   source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
-   They use the native system calls: _open, _close, etc. if they're available
-   (MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
-   (MISSING_SYSCALL_NAMES *is* defined).  */
-
-/* WARNING: All identifiers here must begin with an underscore.  This file is
-   included by stdio.h and others and we therefore must only use identifiers
-   in the namespace allotted to us.  */
