Comment 2 Jakub Jelinek 2002-02-18 12:02:34 UTC 
This is covered in ISO C++ 98 [over] chapter.
By default, g++ now defaults to -pedantic-errors, unless -pedantic or
-fpermissive is given.
If you use -pedantic with g++ 2.96-RH or earlier, you'll get an error too.
The problem is that one overloading candidate is const qualified, the other
one has worse type.

As quick workaround, you can use -fpermissive, long term the code needs to be
fixed.
