transforming a monic polynomial

[Igor Schein <igor@txc.com>]

Hi, is there a command in gp to quickly convert a non-monic polynomial
into a monic one?  nfinit(pol,2).pol would do, but it becomes
senseless when poldisc is big and hard to factor.  I thought
poltschirnhaus(pol) would work, but it doesn't always return monic
polynomials.  

Thanks
Igor
