+- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
+ check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
+ interpreter process. This could cause failures in non-Distutils subprocesses
+ and was unreliable since tests or user programs could modify the interpreter
+ environment after Distutils set it. Instead, have Distutils set the the
+ deployment target only in the environment of each build subprocess. It is
+ still possible to globally override the default by setting
+ MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
+ greater or equal to the default value, the value with which the interpreter
+ was built.
