error with templates and namespaces

["Gary A. Huber" <ghuber at josquin dot ucsd dot edu>]

Hi, gcc folks,

I have some code that doesn't compile.  Apparently, the using
keyword doesn't work in templated functions.  It compiles
fine using the Kuck and Associates compiler.

I'm using egcs-1.1.2-24 on a Pentium box running Red Hat Linux 6.0
I've also tried it with gcc-2.95.2 and I get the same results.

Below is the command I use, the error messages, and the actual code.

gcc -o gcc_test gcc_test.cc -lstdc++

gcc_test.cc: In function `int g<int>(const int &)':
gcc_test.cc:35:   instantiated from here
gcc_test.cc:17: `f' undeclared (first use this function)
gcc_test.cc:17: (Each undeclared identifier is reported only once
gcc_test.cc:17: for each function it appears in.)

Thanks

Gary
