Is it a linker command file problem ?

The __MAKE_SET macro places the function calls into a special section 
and you need to tell the linker to include that section. Doing this 
causes the linker to include the code the executable.

A patch that changes the static definition does not seem correct.

Thomas's PR1119 is included in CVS.
