Linker Message: "discarded section"

[Hartmut Sbosny]

Hello,

I get the linker message

  `.gnu.linkonce.t._ZN3TNT12CurveTntPlotIdE6handleEi' referenced in section
  `.rodata' of FollowCurveWindow.o: defined in discarded section
  `.gnu.linkonce.t._ZN3TNT12CurveTntPlotIdE6handleEi' of FollowCurveWindow.o

i.e. of the structur

  `a' referenced in section `b' of file.o: defined in discarded section
  `a' of file.o

Does anyone know, what it does mean and what could be the reason for this?
(It is a warning message, the linker doesn't abbort.) Oddly enough
it vanishes, if I compile with the "-g" debug option.
I'm using g++ (GCC) 3.3.4 (pre 3.3.5 20040809).


Thanks in advance
Hartmut
