Problem(?) with gcc version 3.0 20010313 (prerelease)

[David Ronis <ronis at ronispc dot chem dot mcgill dot ca>]

I tried using the prerease compiler to build version 3.3 of ddd.  It
dies in the configure step at:

configure:1679: checking whether the C++ compiler (/usr/bin/g++) compiles a simp
le program
configure:1700: /usr/bin/g++ -o conftest -O3 -march=i686 -ffast-math -funroll-lo

configure:1694:22: iostream.h: No such file or directory
configure: In function `int main()':
configure:1696: `cout' undeclared (first use this function)
configure:1696: (Each undeclared identifier is reported only once for each 
   function it appears in.)
configure: failed program was:
#line 1693 "configure"
#include "confdefs.h"
#include <iostream.h>
int main() {
cout << "hello, world!";
; return 0; }


The problem is iostream.h, which is in /usr/include/g++-v3.  When I
manually add -I/usr/include/g++-v3 to CXXFLAGS, I get

configure:1700: /usr/bin/g++ -o conftest -O3 -march=i686 -ffast-math -funroll-loops -fomit-frame-pointer -fforce-mem -fforce-addr -malign-jumps=3 -malign-loops=3 -malign-functions=3 -mpreferred-stack-boundary=3 -fpermissive -I/usr/include/g++-v3   conftest.C  1>&5

Doesn't/Shouldn't 3.0 set a default include path for g++ that makes
sense?  Also there seems to be a problem with the include files.
