Subject: Swap the sense of the -X option vis-a-vis Py_UseClassExceptionsFlag so
X-Git-Tag: v1.5a4~273
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=83b6709d8ec3c81e5434e7fbe898cd60cb395d9f;p=python

Swap the sense of the -X option vis-a-vis Py_UseClassExceptionsFlag so
that class based exceptions are enabled by default.  -X disables them
in favor of the old-style string exceptions.
