Fix problems with memoryview object.  There is still more to do to finish PEP 3118.  The memory-view object needs to be fleshed out and the struct module needs to be modified.

Add macros for checking for long double and defining the size of long double on the platform.  Ctypes and Struct module will both need them.

Fix Issue 1268 with the array module by backing-out the 'w' addition.  All builds will continue to use 'u' for unicode.

Fixes http://bugs.python.org/issue1233 - bsddb.dbshelve.DBShelf.append
was useless due to inverted logic.  Also adds a test case for RECNO dbs
to test_dbshelve.

with a bytes instance (as this will soon print something differently).

Only the filename is still a PyString now.
(We'll need to deal with the default filesystem encoding to do it right.)

to guarantee the claim that it doesn't set an exception.

object with PyString calls and not checking errors.  This caused the display
of syntax errors to be deformed.

Caused file save to fail. Bug 1130.

Changes comparisons between PyBytes and PyUnicode to return unequal
instead of raising TypeError.

locally-defined macros that assume ASCII and only consider ASCII letters.

the range of 255 instead of only 128.

This will undoubtedly require Windows build file changes too.

Get rid of buffer().  Use memoryview() in its place where possible.
In a few places, do things a bit different, because memoryview()
can't slice (yet).

without being initialized.  Also make the code conform to the comment and
return the new object.  This code needs a test!

str.join(...) now applies str() to the sequence elements if they're
not strings alraedy, except for bytes, which still raise TypeError
(for the same reasons why ""==b"" raises it).

tutorial is the right place to mention a file object's encoding.
