Looks like we need to pass complain down into build_base_path.

------- Comment #2 from cjoldfield at gmail dot com 2010-05-25 17:09 -------
Intel 11.1 accepts it, but it doesn't even try to instantiate "one &f(...)".
To see what I mean, try replacing main with:
#include <iostream>
int main()
{
std::cout << sizeof(f<D*, int>(0)) << std::endl;
std::cout << sizeof(f<D*, B*>(0)) << std::endl;
std::cout << sizeof(f<VD*, B*>(0)) <<std::endl;
}
Also for intel, if one forces it to try to instantiate "one &f(...)" by
removing "two &f(...)", it will complain that there is no matching call to
f<...>(0) for all three calls (it should match the second). In this situation,
gcc only complains about the first and the last, which is the expected
behavior.

For the record, both Intel and Comeau accept this. Let's CC Jason...
