+/****************************************************************************
+
+getopt.h - Read command line options
+
+AUTHOR: Gregory Pietsch
+CREATED Thu Jan 09 22:37:00 1997
+
+DESCRIPTION:
+
+The getopt() function parses the command line arguments.  Its arguments argc
+and argv are the argument count and array as passed to the main() function
+on program invocation.  The argument optstring is a list of available option
+characters.  If such a character is followed by a colon (`:'), the option
+takes an argument, which is placed in optarg.  If such a character is
+followed by two colons, the option takes an optional argument, which is
+placed in optarg.  If the option does not take an argument, optarg is NULL.
+
+The external variable optind is the index of the next array element of argv
+to be processed; it communicates from one call to the next which element to
+process.
+
+The getopt_long() function works like getopt() except that it also accepts
+long options started by two dashes `--'.  If these take values, it is either
+in the form
+
+--arg=value
+
+ or
+
+--arg value
+
+It takes the additional arguments longopts which is a pointer to the first
+element of an array of type GETOPT_LONG_OPTION_T, defined below.  The last
+element of the array has to be filled with NULL for the name field.
+
+The longind pointer points to the index of the current long option relative
+to longopts if it is non-NULL.
+
+The getopt() function returns the option character if the option was found
+successfully, `:' if there was a missing parameter for one of the options,
+`?' for an unknown option character, and EOF for the end of the option list.
+
+The getopt_long() function's return value is described below.
+
+The function getopt_long_only() is identical to getopt_long(), except that a
+plus sign `+' can introduce long options as well as `--'.
+
+Describe how to deal with options that follow non-option ARGV-elements.
+
+If the caller did not specify anything, the default is REQUIRE_ORDER if the
+environment variable POSIXLY_CORRECT is defined, PERMUTE otherwise.
+
+REQUIRE_ORDER means don't recognize them as options; stop option processing
+when the first non-option is seen.  This is what Unix does.  This mode of
+operation is selected by either setting the environment variable
+POSIXLY_CORRECT, or using `+' as the first character of the optstring
+parameter.
+
+PERMUTE is the default.  We permute the contents of ARGV as we scan, so that
+eventually all the non-options are at the end.  This allows options to be
+given in any order, even with programs that were not written to expect this.
+
+RETURN_IN_ORDER is an option available to programs that were written to
+expect options and other ARGV-elements in any order and that care about the
+ordering of the two.  We describe each non-option ARGV-element as if it were
+the argument of an option with character code 1.  Using `-' as the first
+character of the optstring parameter selects this mode of operation.
+
+The special argument `--' forces an end of option-scanning regardless of the
+value of `ordering'.  In the case of RETURN_IN_ORDER, only `--' can cause
+getopt() and friends to return EOF with optind != argc.

+/* 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.
+
+   The target may provide the needed syscalls by any of the following:
+
+   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" and add
+      -DREENTRANT_SYSCALLS_PROVIDED to newlib_cflags in configure.host.
+
+   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.host.
+
+   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 newlib_cflags in
+      configure.host.
+
+   4) Define or otherwise provide the regular versions of the syscalls,
+      and do not supply functional interfaces for any of the reentrant
+      calls. With this method, the reentrant syscalls are redefined to
+      directly call the regular system call without the reentrancy argument.
+      When you do this, specify both -DREENTRANT_SYSCALLS_PROVIDED and 
+      -DMISSING_SYSCALL_NAMES via newlib_cflags in configure.host and do
+      not specify "syscall_dir".
+
+   Stubs of the reentrant versions of the syscalls exist in the libc/reent
+   source directory and are provided if REENTRANT_SYSCALLS_PROVIDED isn't 
+   defined.  These stubs call the native system calls: _open, _close, etc. 
+   if MISSING_SYSCALL_NAMES is *not* defined, otherwise they call the
+   non-underscored versions: open, close, etc. when MISSING_SYSCALL_NAMES
+   *is* defined.
+
+   By default, newlib functions call the reentrant syscalls internally,
+   passing a reentrancy structure as an argument.  This reentrancy structure
+   contains data that is thread-specific.  For example, the errno value is
+   kept in the reentrancy structure.  If multiple threads exist, each will
+   keep a separate errno value which is intuitive since the application flow
+   cannot check for failure reliably otherwise.
+
+   The reentrant syscalls are either provided by the platform, by the 
+   libc/reent stubs, or in the case of both MISSING_SYSCALL_NAMES and 
+   REENTRANT_SYSCALLS_PROVIDED being defined, the calls are redefined to
+   simply call the regular syscalls with no reentrancy struct argument.
+
+   A single-threaded application does not need to worry about the reentrancy
+   structure.  It is used internally.  
+
+   A multi-threaded application needs either to manually manage reentrancy 
+   structures or use dynamic reentrancy.
+   
+   Manually managing reentrancy structures entails calling special reentrant
+   versions of newlib functions that have an additional reentrancy argument.
+   For example, _printf_r.  By convention, the first argument is the
+   reentrancy structure.  By default, the normal version of the function
+   uses the default reentrancy structure: _REENT.  The reentrancy structure
+   is passed internally, eventually to the reentrant syscalls themselves.
+   How the structures are stored and accessed in this model is up to the
+   application.
+
+   Dynamic reentrancy is specified by the __DYNAMIC_REENT__ flag.  This
+   flag denotes setting up a macro to replace _REENT with a function call
+   to __getreent().  This function needs to be implemented by the platform
+   and it is meant to return the reentrancy structure for the current
+   thread.  When the regular C functions (e.g. printf) go to call internal
+   routines with the default _REENT structure, they end up calling with 
+   the reentrancy structure for the thread.  Thus, application code does not
+   need to call the _r routines nor worry about reentrancy structures.  */
