Is this the latest version? It does not compile for me, since polynomial.hpp 
uses pow on lines 370 and 372. It needs to include cmath and also needs a 
"using std::pow;" statement.

Second, there are compile errors upon trying to multiply two polynomials 
together (code attached). I am using boost 1.38.0 with gcc 4.3.2 on Linux 
x86_64. The errors I get are of the following form:
