Hi Brad, thanks for replying.

You're welcome. Glad to help. 8)

I have the plugin for visual studio, but it doesn't seem to be 
simulating it correctly. I tested it like this:

/* file test.h */
struct C
    template <class D>
    void foo()
        D d;

    template <>
    void foo<int>()
        int x;

void main()
    C c;

/* end of test.h /*

In the command line:

vc6 doesn't support template specialization.

intel compiles it without problem.

It seems that gccxml is simulating vc6, and not intel... but note that 
I'm using intel c++ v6.0, and in the page says that support is for 
version 5.0... but I believe that the version 5.0 supported template 
specializations too.

Thanks again for the help, and congratulations for this great tool.
