This doesn't seem to work, unfortunately.  Compiling this test program

   // cet3.cxx
   #include <stream.h>
   main() {
     cerr << "This is a test!" << endl ;
   }

with this command line

   gcc -g cet3.cxx -o cet3 -mno-cygwin -lstdc++

produces the attached copious error output.  Also, what happens if I want to
use the math library in my app?  Moreover, this  "solution" requires hacking
my configure scripts and makefiles when they should work automatically. 
Finally, I don't think it's unreasonable for me to say that compiling C++
apps with g++ should work, especially when it worked in a previous release
(b20).

OK, thanks.

Thanks again,
