The attached C++ file as input to gcc-2.2.2 causes an error message
that I believe to be incorrect.  Session transcript:

templates.C: In function `int  main ()':
templates.C:19: template for method `colsOf' doesn't match any in class `Array2D<double>'
templates.C:19: template for method `rowsOf' doesn't match any in class `Array2D<double>'

----------------------------------------------------------------------

The two error messages regarding colsOf and rowsOf seem to be wrong.
If the "const" qualifier is removed from these member functions, no
message results.
