I think you're right.  The 'gcc' man pages says this about --ftemplate-depth:

        -ftemplate-depth-n
            Set the maximum instantiation depth for template classes to n.  A
            limit on the template instantiation depth is needed to detect end-
            less recursions during template class instantiation.  ANSI/ISO C++
            conforming programs must not rely on a maximum depth greater than
            17.

This leads me to conclude that polymake is not portable.
