Hi, experts,

I tried to reuse the .pch to speed the build using the following way:

use /Yc on stdafx.cpp to create the .pch files to a folder
exclude stdafx.cpp in the project, and modify the link option

It success in my machine, but failed in another, got the error message: error C2011: '*' : 'struct' type redefinition

So first I want to ask whether the .pch files are machine sensitive? then secondly, the above approaches workable?

Thanks!
