better than the old error API.

mymalloc.h.  (Since it's a macro, I don't care much.  It is used
internally only; others can use void *.)

Fixed typo in PyArg_VaParse (not PyArgs_*).

instead "posix.error" or "nt.error".

Jack's code).

cgen.py.  Now that cgen.py and cstubs have been quickly renamed, check
in the actual output.  This has some "old-style" names left in
(getilongarg etc.) but these are now take care of by macros in
cgensupport.h (which is now specific to glmodule.c).

Addeed Andrew Kuchling's zlib module.

Added symlinks option to copytree.

Remove unneeded check for '.' / '..' from copytree().
Add some comments.

- which_module() search __main__ last;

- load_inst() no longer checks that the classname really refers to a class.

cPickle-compatible pickle, and pickle must be importable in restricted
mode.  I guess I'll have to make marshal safe.

dirname in sys.path.  This means that you can create a symbolic link
foo in /usr/local/bin pointing to /usr/yourname/src/foo/foo.py, and
then invoking foo will insert /usr/yourname/src/foo in sys.path, not
/usr/local/bin.  This makes it easier to have multifile programs
(before, the program would have to do an os.readlink(sys.argv[0])
itself and insert the resulting directory in sys.path -- Grail does
this).

Note that the expansion is only used for sys.path; sys.argv[0] is
still the original, unadorned filename (/usr/local/bin/foo in the
example).
