Summary:
[las] lim0/lim1 should not exceed 2^31

Detailed description
it seems that if lim0/lim1 exceed 2^31, las does not work properly:

# Error, p = 2203219133 does not divide at (N,x) = (5,29320)
Aborted

where the file rsa768.poly is the one from parameters/polynomials/rsa768.poly, and the file c59.factorbase.roots.gz is the corresponding factor base on the algebraic side (lim = 1100000000 and maxbits = 16).

in the meantime, I've made las give an error when lim0 or lim1 >= 2^31
