Ah that's annoying, thanks for pointing it out! Is it just the MSVC builds? I'm wondering if there's some way I could reproduce this ad-hoc and I don't have access to a Windows machine. I'm doing ccache builds on AArch64 Linux and it's working fine.
Regardless, we're already using `-include-pch` so I think we just need to make sure we use `-fno-pch-timestamp`and set `CCACHE_SLOPPINESS` appropriately?
