Yes, please consider a good book on the "new" C++ ISO standard.

GCC 3.0, 3.1, and 3.2 are increasingly more standards compliant than
GCC 2.95, and the warning you are getting is one of the results.

(If you search the documentation for GCC 3.2, you will find the following
there, so in the future GCC will not just warn, but reject your code:

  The implicit typename extension has been deprecated and will be
  removed from g++ at some point.  In some cases g++ determines that a
  dependant type such as `TPL<T>::X' is a type without needing a
  `typename' keyword, contrary to the standard.
)

Hope this helps,
Gerald
