[CLN-list] CLN switched to C++11

[Jan Rheinländer]

Hi,

the problem is not the MSVC compiler but the configure script. If you
just remove the requirement from configure.ac, then it works fine. I
always comment out the line

AX_CXX_COMPILE_STDCXX_11

and it works. MSVC seems to accept C++11 by default. For some reason, in
spite of that the configure test fails on MSVC.
