Command line options for the xlc compiler behave differently from gcc and clang,
so skip this test case for now when xlc is the compiler.

check_environ() of distutils.utils now catchs KeyError on calling
pwd.getpwuid(): don't create the HOME environment variable in this
case.

platform.dist() is deprecated and slated for removal in Python 3.8. The
upload command itself should also not be used to upload to PyPI, but
while it continues to exist it should not use deprecated functions.

Two kind of mistakes:

1. Missed space. After concatenating there is no space between words.

2. Missed comma. Causes unintentional concatenating in a list of strings.

Use "backslashreplace" instead of "unicode-escape".  It is not
implementation depended and escapes only non-encodable characters.

Also simplify the code.

In distutils.command.install, replace "pliant children" (previously,
it was "pliant slaves") with "helpers".

bpo-32430: Rename Modules/Setup.dist to Modules/Setup

Remove the necessity to copy the former manually to the latter when updating the local source tree.

Patch by Bo Bayles.

CRT v142 is binary compatible with CRT v140.

* Rather than raise TypeError, warn and call list() on the value.

* Fix tests, revise NEWS and whatsnew text.

* Revise documentation, a string is okay as well.

* Ensure 'requires' and 'obsoletes' are real lists.

* Test that requires and obsoletes are turned to lists.

Revert distutils changes of the commit
696b501cd11dc429a0f661adeb598bfaf89e4112 and remove the realm
variable.

* distutils.config: Use the PyPIRCCommand.realm attribute if set
* turtledemo: wait until macOS osascript command completes to not
  create a zombie process
* Tools/scripts/treesync.py: declare 'default_answer' and
  'create_files' as globals to modify them with the command line
  arguments. Previously, -y, -n, -f and -a options had no effect.

flake8 warning: "F841 local variable 'p' is assigned to but never
used".

The Distribution class now explicitly raises an
exception when 'classifiers', 'keywords' and
'platforms' fields are not specified as a list.

* Run gzip with separate command line options (Android understands  '-f9' as the name of a file).
* Creation of a hard link is controled by SELinux on Android.

kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte")
means 1024 bytes. KB was misused: replace kB or KB with KiB when
appropriate.

Same change for MB and GB which become MiB and GiB.

Change the output of Tools/iobench/iobench.py.

Round also the size of the documentation from 5.5 MB to 5 MiB.

We stop support this OS in 2007 with commit
19fab761b71a1687aee3415db3a937b5ce31975d. Let's finish.

It was mostly removed long ago.

See PEP 11.

* Replaced list(<generator expression>) with list comprehension
* Replaced dict(<generator expression>) with dict comprehension
* Replaced set(<list literal>) with set literal
* Replaced builtin func(<list comprehension>) with func(<generator
  expression>) when supported (e.g. any(), all(), tuple(), min(), &
  max())

compiled out-of-tree (builddir != srcdir). (see also bpo-15366)

The AST_H_DIR variable was removed from Makefile.pre.in by the commit
a5c62a8e9f0de6c4133825a5710984a3cd5e102b (bpo-23404).

AST_H_DIR was hardcoded to "Include", so replace the removed variable
by its content.

Remove also ASDLGEN variable from sysconfig example since this
variable was also removed.
