gdal @2.2.0: broken on non-C++11 setups

[mojca (Mojca Miklavec)]

gdal 2.2.0 is broken on non-C++11 setups, but the compilation should theoretically still work with C++03.

The most important part would be to pass --without-cpp11 to configure.args when not using C++11. The way to check that is probably by testing for stdlib and declare C++11 support non-existent when it's not libc++, even if that's not exactly correct.

Once you do that, one of the major issues becomes the dance around isnan() and isinf(). The master branch / trunk works much better in this respect due to addition of

#elif defined(__cplusplus) && defined(HAVE_STD_IS_NAN) && HAVE_STD_IS_NAN

in port/cpl_port.h and on 10.7 it leads to successful compilation. 10.6 would probably need a newer compiler, I didn't test yet.

I'm sorry, I didn't know I would manage to fix it so quickly, else I wouldn't open an issue here. Here's a PR:
