All the problems come from the following: Be `Base<>' a template
and `Derived<>' a template derived from `Base'. In `Derive' we use
a `Base' element, e.g a function `dim()':

template <typename T>
class Base {
  public:
    int dim();
    ...
};

template <typename T>
class Derived : public Base<T> {
  public:
    int use_dim_1() {return dim();}  // older g++: accepted
									    // newer g++: error: `dim' not declared
    int use_dim_2() {return Base<T>::dim();}  // ok
    ...
};

The newer g++ want have a more explicite name  - it is easy to fix.

Thanks Daniel, for all the effort. Under

I put the zipped tar file

  bracketing_to_hdr-0.21-20060818.tar.zip.

It contains a version fixed for g++ 4.1.1. The pathnames in the 
archive are relative to the directory "plug-ins", i.e. to install so: 

Copy the ~.tar.gz file into the CinePaint directory "plug-ins" and 
  make this directory to the current.
gunzip ~.tar.gz   (creates ~.tar file)
tar xvf ~.tar     (unpackes tar archive into "./bracketing_to_hdr") 
cd ..             (go to the CinePaint root dir)
./config.status   (creates Makefile(s) and .deps files)
make

Before one could save the old bracketing_to_hdr directory by renaming.

First I wanted to provide a patch file, but I have to train yet with 
diff and patch. 

Greetings,
Hartmut
