Near the top of the generated libtool script there should be

        available_tags=" CXX"

And near the end just under "# ### BEGIN LIBTOOL TAG CONFIG: CXX"
there should be

        CC="g++"

Which is how it's supposed to know that "g++ ..." means C++.  You can
run that command with "sh -x" to see perhaps where it goes wrong,

        cd cxx
        /bin/sh -x ../libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I.. 
-D__GMP_WITHIN_GMP -I.. -g -O2 -fomit-frame-pointer -mcpu=pentiumpro 
-march=i486 -c -o isfuns.lo `test -f isfuns.cc || echo './'`isfuns.cc

Actually you don't need the whole big set of options just to see what
libtool is doing, it should be enough to run something like

        /bin/sh -x ../libtool --mode=compile g++ -c -o isfuns.lo isfuns.cc
