Now, if there exists a debug version of the .gch file and I compile for release, there will be a warning that the .gch file is compiled with different settings, and the precompiled file will not be used.

Should not the PCH end up in directory like "bin/debug" or "bin/release" and consequence used only when
building the right variant, when using Boost.Build? Is this not happening, or there's some other issue?
