+* 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.
