* Description:

* 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.  

*
