Right. I understood that to be the case its just your statement above
What I've put into libtool (on Todd's suggestion) is a check for c++rt0
in $(CC) -dumpspecs. If it exists then the compiler is used to link
(shared) libraries, if not the linker is used and is always passed
c++rt0. My fear is that this will (continue to) not work for
Do cc/c++ include c++rt0 only if necessary? How does it make this
decision? Or does c++ include it and cc not.
