Thanks everyone. That works and a neat little trick!

Hi Jason,

I'm pretty sure you just get one precompiled header (I don't think you could precompile two headers and then merge the results in any meaningful way). You should be able to #include common.pch from inside appspecific.pch because common.pch is just a text file (with a funny suffix to tip off the compiler that you will be precompiling it).
