Choosing the right CPU type

[Tuomas Pellonperä]

I will be installing the latest (4.3.1) GMP release on an Acer Veriton
M261 box with Intel Celeron 430 processor (1.80 GHz).

config.guess gives me
`core2-pc-linux-gnu' (I have Ubuntu 9.04). Is this the best option to
give to configure, or does my CPU have specific support?

(I am looking at the list on
<http://gmplib.org/manual/Build-Options.html#Build-Options>, and I don't
see a better option.)

Much oblige!
