Subject: Backport of rev1.57:
X-Git-Tag: v2.2.3c1~221
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0e44fa9c299e1fee551fce8b4037ed3117a2458b;p=thirdparty%2FPython%2Fcpython.git

Backport of rev1.57:
 Make the Distribution() constructor forgiving of unknown keyword
 arguments, triggering a warning instead of raising an exception.  (In
 1.5.2/2.0, it will print to stderr.)
