parsing

	* Lib/macpath.py: don't return trailing colon for dirname()
	(XXX won't do for volume names -- but otherwise glob(':*:*.py')
	loops forever)
	* Lib/traceback.py: print SyntaxError correctly
	* Lib/stat.py: moved to posixstat.py; added macstat.py which has
	the constants for the Mac; and created new stat.py which includes
	the right one
	* Lib/urllib.py: fix caching bug (by disabling the cache)

	the cache!)

	millisleep(); document clock()

	* Doc/ref6.tex (section{Assignment statements}): added warning
	about overlaps in lhs of assignment (e.g. "i, x[i] = 1, 2")

Makefile.in: remove lib*.a before creating new one.

Pass value of OPT from configure environment to Makefile.
Add check for limits.h.
Use <directory>/libreadline.a instead of -lreadline.

pindent.py: use /usr/local/bin/python;
pathfix.py: new script to fix #! lines in a group of scripts.

(NT changes for posixmodule.c re-invented by Guido.)

	removed references to {ato{f,i,l},index}_error

	index/rindex is a wrapper that raises index_error (which is now
	always ValueError)

	index/rindex (raising and catching an exception is much more
	expensive than returning and testing -1)

info about windows stdwin, more about gnu getopt, correct typo

arguments (adding __delattr__ was deemed too much overhead)

	more trouble than it's worth at CWI and most other people seem to
	install Python in the default (/usr/local) anway.  Changed comment
	describing --prefix in Makefile.in

	regex.match() result, and wrong logic in getfirstmatchingheader()
	when the same header occurs twice consecutively

	describe tuple()

	* Doc/libposixfile.tex: use tableiii instead of tableii, so
	partparse will work again (I know, chicken!)

	* Doc/libthread.tex: Added get_ident(); updated text on module
	availability

	* Doc/myformat.perl: Added sub do_cmd_Cpp

	and __setattr__ support to override getattr(x, name) and
	setattr(x, name, value) for class instances.  This uses a special
	hack whereby the class is supposed to be static: the __getattr__
	and __setattr__ methods are looked up only once and saved in the
	instance structure for speed
