It looks like you could fix this by adding

  #include <cstring>

in the include statements at the begiining of the sfc_pres_temp_rd.cpp file.
You will probably need to add this also to the other example files in that 
directory to get a successful make, testing all the examples.  These problems
were fixed in later versions.

After setting CXX='', you would have to run "make clean" and rerun the
configure script, before running "make check".  Doing things in that
order, you should not have gotten any C++ errors.  But it sounds like
you're close to getting the C++ API and examples to work anyway, so you
might as well finish with that approach.

By the way, even though WRF recommends using version 3.6.2, I expect it would
work fine linking against 4.1.1 also.  We know there are users using WRF with
4.1.1 successfully ...
