Currently the --import/export-maps options only support VC++ and use the 
template instantiation export syntax (which is quite peculiar) directly.

I played with GCC's __attribute__ ((visibility("default"))) syntax in the
same context and it seems to work ok. So I went ahead and added it to the
code generator. Here is a pre-release binary with this functionality:

Can you try it on your project and let me know if everything works as
expected? If it works, then I will commit this for the next release of
XSD.

Thanks,
