I noticed a build failure after making a change to `llvm/include/llvm/Support/Compiler.h` .
https://github.com/llvm/llvm-project/pull/143222#issuecomment-2971658629
The build log shows the following error:
> fatal error: file 'C:\Users\tcwg\llvm-worker\flang-arm64-windows-msvc\llvm-project\llvm\include\llvm\Support\Compiler.h' has been modified since the precompiled header 'C:/Users/tcwg/llvm-worker/flang-arm64-windows-msvc/build/tools/flang/lib/Parser/CMakeFiles/FortranParser.dir/./cmake_pch.cxx.pch' was built: size changed (was 27102, now 27125)
It appears that the build system does not properly detect and rebuild the precompiled header when one of its dependencies is updated.
