This is one of GCC's genuine limitations... template instantiation...
However CYGNUS made a patch for gcc which fixes this problem...
ftp://ftp.cygnus.com/pub/g++/gcc-2.7.0-repo.gz

However if you dont feel like recompiling your compiler use the #pragma
interface, #pragma implementation "filename.h" stuff described in the
gcc info thingy..
