[SOLVED] g++ from gcc-12.2.0 not compliant with std=C++11

Trying to build pass 2 of gcc-12.2.0 but I can't get past libcody test in libcody configure which wants __cplusplus=201103 or whatever, not >. Seems a stupid test 12 years later and gcc claims to have been fully compliant with C++11 since gcc-5.

I don't know where __cplusplus is set or whether it changes when I put something like -std=gnu++2b in CXXFLAGS and I can't find the exact test used by libcody configure about lines 2490 to 2520 where C++11 is tested several times but in conftest.c wherever it is.

The solution was not to specify any standard for g++ in CXXFLAGS, which leaves me wondering what sort of compiler is built of parts compatible with a range of C++ standards. Grooving on this new system, though. Do without a lot of these groups, I think.
