One warning though: since gcc became gcc-3.2, I haven't been able to
build a working cxx.  It must be trying to call gcc, which is 3.2,
but cxx's name mangling is incompatible with 3.2 so there are always
missing symbols (like cout). 
Hmm, works for me[tm] on sid with cxx cxx-6.5.9.31. My comp.config
looks like this:

(Hmm, 3.2.2 should really be 3.2.3. Still works :)
Aha, I had an identical file minus the -std strict_ansi. But with those, it gives me compiler errors: 

zither:/# cxx /tmp/bye.C -o /tmp/bye
cxx: Error: /tmp/bye.C, line 4: identifier "cout" is undefined
 cout << "Hello world" << endl;
--^
cxx: Error: /tmp/bye.C, line 4: identifier "endl" is undefined
 cout << "Hello world" << endl;
---------------------------^
cxx: Info: 2 errors detected in the compilation of "/tmp/bye.C".
zither:/# more /tmp/bye.C
#include <iostream>
int main()
{
 cout << "Hello world" << endl;
return 0; }
Funny, because at the top of cxx's iostream.hxx it says something about can't define -D__STD_STRICT_ANSI and use iostream, but that error doesn't show up. Without -std strict_ansi, it gave: 

# cxx -v /tmp/bye.C -o /tmp/bye

I'm confused -- how did you get this to work? I'm really not a C++ person, but would love to provide a working cxx to those who need it. 

Thanks,
