Subject: PyUnicode_KIND() uses _Py_RVALUE() (#100060)
X-Git-Tag: v3.12.0a4~281
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=abbe4482ab914d6da8b1678ad46174cb875ed7f6;p=thirdparty%2FPython%2Fcpython.git

PyUnicode_KIND() uses _Py_RVALUE() (#100060)

The PyUnicode_KIND() macro is modified to use _Py_RVALUE(), so it can
no longer be used as a l-value.
