It seems to know that c++ is the C++ compiler, but then uses cc anyway:
I doubt that libtool can be smart enough to intuit when the C++
compiler needs to be used for linking when the program being linked is
C. The only way it could tell this is via library dependencies. Just
supplying the library dependencies is not enough.
C++ introduces a new wrinkle in that there are now often 3 or 4
different C++ variants available based on C++ standard level, and
library options (e.g. different C++ STL library implementations).
Things have changed quite a lot in the past several years when it
comes to C++.
In addition to being linked using the C++ compiler, the correct
options would need to be passed to the C++ compiler so that the
correct standard level and libraries are used.
