"This should also explain the need for the /Zm option. The compiler
needs to ensure it has a contiguous address space for the heap we create
the PCH from.

I turned off pre-compiled headers for my compilations, just in case.
This may explain the different requirements, but not my confusion?
Perhaps it is to do with getting the compiler re-started so it
finds the contiguous space?

(It fails C1060 immediately without appearing to do anything,
whereas on the first try, it takes some seconds before failing).
