an exception from errno, with a supplied filename (primarily used by
IOError and OSError). If class exceptions are used then the exception
is instantiated with a 3-tuple: (errno, strerror, filename). For
backwards compatibility reasons, if string exceptions are used,
filename is ignored.
PyErr_SetFromErrno(): Implement in terms of
PyErr_SetFromErrnoWithFilename().
OSError. The EnvironmentError serves primarily as the (common
implementation) base class for IOError and OSError. OSError is used
by posixmodule.c
Also added tuple definition of EnvironmentError when using string
based exceptions.
(1) If a sequence S is shorter than len(S) indicated, don't fail --
just use the shorter size. (I.e, len(S) is just a hint.)
(2) Implement the special case map(None, S) as list(S) -- it's faster.
must be enabled here, otherwise the errno we set on overflows is not
the errno that's being read by compile.c. Wonder how many other files
that do their own "#include config.h" need this too :-(
(Because of the structure of autoconf, it's not so simple to get this
into config.h...)
the filename contains at least a rudimentary pathname.
(The bad part is that we need to call getcwd() because only a prefix
of ".\\" is not enough -- we prefix the drive letter.)
and lists; if the size is negative, raise an exception. Also raise an
exception when an undefined type is found -- all this to increase the
chance that garbage input causes an exception instead of a core dump.

tp_as_sequence or tp_as_mapping structure is made without checking it
for NULL first.
the code here becomes much simpler. In particular: abs(), divmod(),
pow(), int(), long(), float(), len(), tuple(), list().

A few other cosmetic things, such as properly reindenting slice().
old value in a temporary and XDECREF it only after then new value has
been set. This prevents the (unlikely) case where the destructor of
the member uses the containing object -- it would find it in an
undefined state.
