I cant understand why, if you want an x86 target, you don't just grab a 
second-hand WINPC and bang Linux on it, and cross mount a source 
directory and compile on it using the command line - no need even for 
screen and keyboard

My Pi code was all prototyped on a fast compiling x86 machine prior to 
mounting the source directory on the pi and then typing "make clean; make;"
Cross compiling works, but is a lot easier to have the right CPU and 
libraries handy for a target to compile and test upon.
