Re: libtool uses cc to link a mixed C/C++ project and fails to find operator new

Dunno what is wrong in Yuri's FreeBSD environment

In my environment /usr/bin/cc is link to gcc , linked to gcc-5.5.0, and 
c++ is linked to g++, linked to g++-gcc-5.5.0.

In my environment.
At configure time both compiles are detected as usable. At build time I 
could see:
- for C code:
   CC foo
   CCLD bar
- for C++ code:
   CXX alice
   CXXLD bob
And projects builds just fine!
Conclusion - there is no defect neither in libtool nor in automake nor 
in project autotool files.

Reporter still does not provide feedback with information from 
configuration time (requested in a previous post) => resolution is - 
broken build environment.
