Missing concept check instantiations on sparc-sun-solaris2.8 cross sometimes

[Brad Spencer <spencer at infointeractive dot com>]

For very simple programs the gcc-3.3 cross compiler for
sparc-sun-solaris2.8 (on i686-pc-linux-gnu), some of the concept
checking helpers do not get instantiated.  Is this a known issue?  The
compiler I am using includes the patch discussed in
http://gcc.gnu.org/ml/libstdc++/2003-05/msg00247.html 

I have determined that by using the std::copy() algorithm (for any
types?) causes the templates to be instantiated (or something) and the
problem goes away.  I hadn't noticed it until now because this never
shows up in bigger (real) programs.

For example (sorry about the noise), consider the following program.

$ cat test_nothing.cc
#include <iostream>
#include <algorithm>

int
main()
{
  char a, b;
  //  std::copy(&a, &a + 1, &b);
  std::cout << "Hello, world!" << std::endl;
  return 0;
}

With the copy line commented out, I get linker errors reporting that
some of the instantiations are missing.   Uncommenting it fixes the
problem.  It seems that iostream is assuming the presence of some
instantiations that aren't always there.  Perhaps there are some
missing from concept-inst.cc?  I'm not that familiar with exactly how
this mechanism works.
