#230075 ] dbmmodule build fails on Debian GNU/Linux unstable (Sid)".

- Build bsddb module with libdb3 if it's available.  It also fixes a bug that
  causes the build of bsddb to fail on Debian if bsddb3-dev is installed.

strings, not C strings)

removed USE_PYTHON defines, and related sre.py helpers

skip calling the subx helper if the template is callable.
interestingly enough, this means that

	def callback(m):
	    return literal
	result = pattern.sub(callback, string)

is much faster than

	result = pattern.sub(literal, string)

check to the test suite.

added a few missing exception checks in the _sre module

removed (conceptually flawed) getliteral helper; the new sub/subn code
uses a faster code path for literal replacement strings, but doesn't
(yet) look for literal patterns.

added STATE_OFFSET macro, and use it to convert state.start/ptr to
char indexes

Do not set the Expat handlers if it is. Fixes PyXML bug #473195.

'slotdef' structure typedef and 'struct wrapperbase'.  By adding the
wrapper docstrings to the slotdef structure, the slotdefs array can
serve as the data structure that drives add_operators(); the wrapper
descriptor contains a pointer to slotdef structure.  This replaces
lots of custom code from add_operators() by a loop over the slotdefs
array, and does away with all the tab_xxx tables.

also restored SRE Unicode support for 1.6/2.0/2.1

    1. configure doesn't handle HP-UX release numbers

make it easier to look those up.  Also, refer to the file() function/
constructor instead of open() now that that is where the actual docs for
those parameters live.
This closes SF bug #472004.

should have been checked in as part of patch #470254.

use the correct base for a buffer object in _PyBuffer_FromObject.

This appears to be a case of a missing \n\ in a multiline string
literal.

This patch should also be applied to the 2.2b1 trunk.

    This patch implements what we have discussed on python-dev late in
    September: str(obj) and unicode(obj) should behave similar, while
    the old behaviour is retained for unicode(obj, encoding, errors).

    The patch also adds a new feature with which objects can provide
    unicode(obj) with input data: the __unicode__ method. Currently no
    new tp_unicode slot is implemented; this is left as option for the
    future.

    Note that PyUnicode_FromEncodedObject() no longer accepts Unicode
    objects as input. The API name already suggests that Unicode
    objects do not belong in the list of acceptable objects and the
    functionality was only needed because
    PyUnicode_FromEncodedObject() was being used directly by
    unicode(). The latter was changed in the discussed way:

    * unicode(obj) calls PyObject_Unicode()
    * unicode(obj, encoding, errors) calls PyUnicode_FromEncodedObject()

    One thing left open to discussion is whether to leave the
    PyUnicode_FromObject() API as a thin API extension on top of
    PyUnicode_FromEncodedObject() or to turn it into a (macro) alias
    for PyObject_Unicode() and deprecate it. Doing so would have some
    surprising consequences though, e.g.  u"abc" + 123 would turn out
    as u"abc123"...

[Marc-Andre didn't have time to check this in before the deadline.  I
hope this is OK, Marc-Andre!  You can still make changes and commit
them on the trunk after the branch has been made, but then please mail
Barry a context diff if you want the change to be merged into the
2.2b1 release branch.  GvR]

    In Include/, marshal.h declares both
    PyMarshal_ReadLongFromFile()
    and PyMarshal_ReadShortFromFile(),
    but the second is missing from marshal.c.

[Shouldn't the return type be declared as 'short' instead of 'int'?
But 'int' is what was in marshal.h all those years...  --Guido]

This adds unsetenv to posix, and uses it in the __delitem__ method of
os.environ.

(XXX Should we change the preferred name for putenv to setenv, for
consistency?)

This was submitted by Moshe, but apparently he's too busy to check it
in himself.  He wrote:

    Here is a function in GNU readline called add_history,
    which is used to manage the history list. Though Python
    uses this function internally, it does not expose it to
    the Python programmer. This patch adds direct interface
    to this function with documentation.

    This could be used by friendly modules to "seed" the
    history with commands.

199712 didn't have dlfcn.h, or that it wouldn't conflict with the other
stuff defined.
