  ***=== FUNCTIONS ============================================================
+ *
  ** Function:	void			istream_setup
- *			PROTO_S ((void))
+ *			(void)
  ** Exceptions:
+ *
  * This function initialises the input stream facility.  It should be called
  * before any other istream manipulation function.
+ *
  ** Function:	void			istream_init
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
  ** Exceptions:
+ *
  * This function initialises the specified istream not to read from any file.
+ *
  ** Function:	BoolT			istream_open
- *			PROTO_S ((IStreamP istream, CStringP name))
+ *			(IStreamP istream, CStringP name)
  ** Exceptions: XX_dalloc_no_memory, XX_istream_read_error
+ *
  * This function initialises the specified istream to read from the file with
  * the specified name.  The name should not be modified or deallocated until
  * the istream has been closed.  If the file cannot be opened, the function
  * returns false. If the file is opened successfully, the function returns
  * true.
+ *
  ** Function:	void			istream_assign
- *			PROTO_S ((IStreamP to, IStreamP from))
+ *			(IStreamP to, IStreamP from)
  ** Exceptions:
+ *
  * This function assigns the from istream to the to istream.  The from istream
  * should not be used again.
+ *
  ** Function:	BoolT			istream_is_open
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
+ *
  * This function returns true if the specified istream is reading from a file,
  * and false otherwise.
+ *
  ** Function:	BoolT			istream_read_char
- *			PROTO_S ((IStreamP istream, char *c_ref))
+ *			(IStreamP istream, char *c_ref)
  ** Exceptions:	XX_dalloc_no_memory, XX_istream_read_error
+ *
  * This function reads the next character from the specified istream (and
  * advances the character pointer).  If a character is read then the character
  * is assigned to the reference argument, and the function returns true.  If
  * the end of file is reached, the function returns false.  If the character
  * read is a newline, then the istream's line count is incremented.
+ *
  ** Function:	BoolT			istream_peek_char
- *			PROTO_S ((IStreamP istream, char *c_ref))
+ *			(IStreamP istream, char *c_ref)
  ** Exceptions:	XX_dalloc_no_memory, XX_istream_read_error
+ *
  * This function reads the next character from the specified istream (but does
  * not advance the character pointer).  If a character is read then the
  * character is assigned to the reference argument, and the function returns
  * true.  If the end of file is reached, the function returns false.
+ *
  ** Function:	IStreamStatusT		istream_read_escaped_char
- *			PROTO_S ((IStreamP istream, char *c_ref))
+ *			(IStreamP istream, char *c_ref)
  ** Exceptions:	XX_dalloc_no_memory, XX_istream_read_error
+ *
  * This function reads a character sequence from the specified istream, and
  * parses it as an escaped character sequence.  Normally, the character to
  * which the sequence evaluates is assigned to the reference argument and
  * ``ISTREAM_STAT_SYNTAX_ERROR'' is returned.  If any of the characters read
  * are newline characters, then the istream's line counter will be incremented
  * for each newline.
+ *
  ** Function:	void			istream_inc_line
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
  ** Exceptions:
+ *
  * This function increments the specified istream's line counter.  It should
  * only really be called as specified in the documentation for the
  * ``ISTREAM_READ_CHAR'' macro.
+ *
  ** Function:	unsigned		istream_line
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
  ** Exceptions:
+ *
  * This function returns the line number of the specified istream (one more
  * than the number of newlines that have been read).
+ *
  ** Function:	CStringP		istream_name
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
  ** Exceptions:
+ *
  * This function returns the name of the file from which the specified istream
  * is reading. The return value should not be modified or deallocated.
+ *
  ** Function:	void			istream_close
- *			PROTO_S ((IStreamP istream))
+ *			(IStreamP istream)
  ** Exceptions:
+ *
  * This function closes the specified istream.
+ *
