If you haven't seen my followup to Earnie's 2nd posting on this, it'll
soon show up on the list and I won't repeat myself. 

I'll summarize quickly: GCC has *always*, and still does, called the C++ 
compiler when it sees certain suffix, and still does. That has nothing to 
do with linking however, and GCC has *never* linked in the C++ runtime if 
invoked as gcc as opposed to g++/c++.

The only difference in gcc-2.8.0 is that g++ no longer links in the
deprecated libg++ automatically. Before 2.8.0, c++ will only link in
libstc++ and g++ will add libg++ in addition to libstdc++. Now, both
c++ and g++ are identical in behaviour.

It is not a bug, and the behaviour remains the same (minus, and possibly
plus, a few bug fixes in how the driver works). Of course, I'm talking
about gcc2 days; g++ 1.x was a different beast altogether.

I do sympathize with folks who misunderstand how the language drivers in 
gcc is supposed to work; the documentation is not at all clear, and I
obviously haven't done anything to improve it.

Any followups to gcc or egcs related mailing lists please.

Mumit
