You could always just add -lstdc++ to the oprofiled_LDADD variable.

This would be a fault, IMO.

Why?

I do not think getting gcc to link -lstdc++ is a good idea either, but
it doesn't have much more hack value than the solution you propose below
IMHO.

It's the hack that using g++ performs.

The problem is trying to link a c-program against a c++-library. This
doesn't work in general, esp. not with g++, unless such a c++ library is
specially designed for such purposes.

Well, g++ does the same extension filtering that gcc does. It will compile .c as C and .C, .cc, .cxx, .cpp as C++. If either finds source in the form of the other then the compilation type is changed.

This seems IMHO to be a terrible hack. I've found automake to be quite
flexible so far; am I hitting one of its limitations ?

Another solution would be to use a BUILD_CC variable. Set BUILD_CC to the value of $(CC) for C and the value of $(CXX) for C++ and use $(BUILD_CC) in the rules.
