Subject: Issue #18441: Make test.support.requires('gui') skip when it should.
X-Git-Tag: v2.7.6rc1~278
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=09eb26fe26d533974f38907328b1160cbcfd6d21;p=thirdparty%2FPython%2Fcpython.git

Issue #18441: Make test.support.requires('gui') skip when it should.
(Consolidating this check and various checks in tkinter files and moving them
to test.support and test.regrtest will be another issue.)
