get_rfc_url():  New function; returns the URL for a numbered IETF RFC.

do_cmd_rfc():  Use get_rfc_url() instead of hard-coding in the HTML
               formatting.

do_cmd_seerfc():  New function.

do_env_definitions():  Small change to avoid "local".

in command-line options, and in two phases at that: first, we expand
'install_base' and 'install_platbase', and then the other 'install_*'
options.  This lets us do tricky stuff like
    install --prefix='/tmp$sys_prefix'
...oooh, neat.

Simplified 'select_scheme()' -- it's no longer responsible for expanding
config vars, tildes, etc.

Define installation-specific config vars in 'self.config_vars', rather than
in a local dictionary of one method.  Also factored '_expand_attrs()' out
of 'expand_dirs()' and added 'expand_basedirs()'.

Added a bunch of debugging output so I (and others) can judge the
success of this crazy scheme through direct feedback.

options.

Fix 'sdist.write_manifest()' to respect the value of dry_run.

MSG_DONTWAIT.  Reported by Fredrik Lundh.

1)  Adds MSG_DONTWAIT if defined (I needed this)
2)  Spells "coreectly" correctly ;-)

the path to save a relative path by prefixing it with os.sep (':').
Also fix an indent inconsistency in the same function.

Noted by Skip Montanaro <skip@mojam.com>.

you are trying to use Py_TRACE_REFS.

I think that after this patch, all objects in the os module (with names
that don't start with "_") that can have docstrings, do, on Linux at
least.

Also fix a nit in one of my spawn* docstrings.

validate_numnodes():  Added comment to explain the sometimes idiomatic
        usage pattern.

project.  [However I didn't add the other changes in his patch, which
were just taking away the source code control stuff -- this doesn't
hurt and would come back as soon as I make another change. --GvR]

a reminder to myself).

Adds bztar format to generate .tar.bz2 tarballs

Uses the -f argument to overright old tarballs automatically, I am
assuming that if the old tarball was wanted it would have been moved or
else the version number would have been changed.

Uses the -9 argument to bzip2 and gzip to use maximum
compression. Compress uses the maximum compression by default.

Tests for correct value for the 'compress' argument of make_tarball. This
is one less place for someone adding new compression programs to forget to
change.

Improvements:
- does no longer need any extra memory
- has no relationship to tstate
- works in debug mode
- can easily be modified for free threading (hi Greg:)

Side effects:
Trashcan does change the order of object destruction.
Prevending that would be quite an immense effort, as
my attempts have shown. This version works always
the same, with debug mode or not. The slightly
changed destruction order should therefore be no problem.

Algorithm:
While the old idea of delaying the destruction of some
obejcts at a certain recursion level was kept, we now
no longer aloocate an object to hold these objects.
The delayed objects are instead chained together
via their ob_type field. The type is encoded via
ob_refcnt. When it comes to the destruction of the
chain of waiting objects, the topmost object is popped
off the chain and revived with type and refcount 1,
then it gets a normal Py_DECREF.

I am confident that this solution is near optimum
for minimizing side effects and code bloat.

socklen_t (unsigned int) for most size parameters.  Apparently this is
part of the UNIX 98 standard.

[GvR: the changes to configure.in etc. that I just checked in make
sure that socklen_t is defined everywhere, so I deleted the little
part of Jack's mod to define socklen_t if not in GUSI2.  I suppose I
will have to add it to the Windows config.h in a minute.]

doesn't use the special header file for select anymore.

has a few slightly different calls from the old one.

the change to regrtest.py to unload all newly imported modules did
something bad to the threads -- and I realized that they would never
stop!

This uses the same precautions when trying to find a temporary
directory as when the actual tempfile is created (using O_CREAT and
O_EXCL).  On non-posix platforms, nothing is changed.

Don't build the _tkinter project from Build, only the one from Extensions:Imaging, which now drops its resulting .slb into the PlugIns folder.

The fix also adds support for POSTing to an https URL
