prototype does not match any in class - maybe it should

[Peter Cech]

Hi,

I got compiler error like this yesterday:

../src/PerSliceImageFilter.txx:79: error: prototype for `void 
   PerSliceImageFilter<TInputImage, TOutputImage>::SetOutputSlice(const 
   itk::Image<typename TOutputImage::PixelType, 
   (PerSliceImageFilter<TInputImage, TOutputImage>::OutputImageDimension - 
   1)>*, typename itk::ImageToImageFilter<TInputImage, 
   TOutputImage>::InputImageType::SizeValueType)' does not match any in class `
   PerSliceImageFilter<TInputImage, TOutputImage>'
../src/PerSliceImageFilter.h:87: error: candidate is: void 
   PerSliceImageFilter<TInputImage, TOutputImage>::SetOutputSlice(const 
   itk::Image<typename TOutputImage::PixelType, 
   (PerSliceImageFilter<TInputImage, TOutputImage>::OutputImageDimension - 
   1)>*, typename itk::ImageToImageFilter<TInputImage, 
   TOutputImage>::InputImageType::SizeValueType)
../src/PerSliceImageFilter.txx:79: error: template definition of non-template `
   void PerSliceImageFilter<TInputImage, TOutputImage>::SetOutputSlice(const 
   itk::Image<typename TOutputImage::PixelType, 
   (PerSliceImageFilter<TInputImage, TOutputImage>::OutputImageDimension - 
   1)>*, typename itk::ImageToImageFilter<TInputImage, 
   TOutputImage>::InputImageType::SizeValueType)'

However hard I look, both error and suggested methods are exactly the
same (there is only one SetOutputSlice in my class). Night sleep did not
help, they look the same this morning.

Compiler version is
gcc (GCC) 3.3.5  (Gentoo Linux 3.3.5, ssp-3.3.2-3, pie-8.7.6.7)
but I got the same error with 3.3.4 and 3.2.3. It seems that 3.4.3 is
not affected, but I'm not sure as it chokes on different place.

Is it bug in gcc or am I just doing something extremly stupid?
