  Determine following buffer sizes for outerw - see minbufsize.h
	MAXATTRSIZE
	MAXCOMMENTLINE

	OUTBUFSIZE
	OUTVARBUFSIZE
	PARSAVSIZE
	MAXPATHSIZE
	TOKEN
	TOTATTRSIZE
	MAXVARNAMESIZE

  27 Jan 96	1) parametrized & sanity checked some buffer sizes 
		2) allowed method maker to optionally specify them by 
	     use of precompilation switch IOBUF_INCLUDE.  If specified, 
	     it should be set = to a valid include file including 
	     (sorry for the pun!) its punctuation; eg,
	     -DIOBUF_INCLUDE='"/my_method/src/my_method_buf_sizes.h"'
		    This file may define any or all of the symbols
	     MAXATTRSIZE, MAXCOMMENTLINE, MAXDATUMSIZE, MAXOBJECTPARAMSIZE, 
	     MAXPATHSIZE, PARSAVSIZE, TOTATTRSIZE, & MAXVARNAMESIZE.
	     (see text below for defns).  wjs

  5 Mar 96   moved minima to 'minbufsize.h' and iobuf_include reference 
              is there, also.  minbufsize.h can, then, be included in an
              inner.c and it will include any user-specified values   clh
