Templates and Linking

Hi,

Does anyone know how to get around this error which is reported during
linking when using the STL:

Table.o(.data+0xc):Table.cc: multiple definition of
`__default_alloc_template<false, 0>::free_list'
Main.o(.data+0x0):Main.cc: first defined here

The exact same code compiles fine on gcc2.7.2 with djgpp. Is there any
reason why template intansiation is different?

Attached is a trivial example.

regards,

Mike.
