Subject: _AC_PROG_CXX_STDCXX_EDITION_TRY: fix typo in variable name
X-Git-Tag: v2.72c~89
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f460883035ef849a2248b1713f711292ec19f4f0;p=thirdparty%2Fautoconf.git

_AC_PROG_CXX_STDCXX_EDITION_TRY: fix typo in variable name

The typo causes "ac_prog_cxx_stdcxx" to be always set to "cxx11",
regardless of whether the C++ compiler supports C++11.
