You should fix the code. Make use of the `typename' keyword.

You don't need to bother. GCC will automatically search for standard
headers in the right location. The C++ standard compliant headers are
in the /usr/include/c++ directory. The headers in the
/usr/include/g++3 directory are from an older libstdc++ version which
was not (that) compliant to the C++ standard. Run g++ with the -v
switch to find out where it finds its files and which commands are
executed to run the different stages of compilation.

You could have had a look at gcc.gnu.org to find out. But yes, this
is a stable GCC release (Feb 05 2003).
