[Bug c++/18047] New: Wrong precedence between equality (==, !=) and < operators

[veksler at il dot ibm dot com]

gcc-4.0 gives operator== higher precedence than operator<, which is against
5.10 paragraph 1:
  "Note: a<b == c<d is true whenever a<b and c<d have the same truth value"

$ cat t.cpp
int main()
{
   if ( 2 < 0 == false)
       return 0;  // should return here
   return 1;
}

$ /home/veksler/gcc-4.0-20041017/bin/g++ t.cpp
$ ./a.out ; echo status=$?
status=1
