Determining Processor Vender

Dose anyone know of a cross-platform method for determining the vendor of a processor? Under linux I can check /proc/cpuinfo. What I'd like to be able to do is determine if a processor is AMD or Intel, so that I can use the appropriate numerical libraries for my application. Regards, Aquil -- h
