commit 67a798c0023326561e07313fd732162f0c053bd0

    remove PCH file before generating it
    
    Compilers do not necessarily output all includes files when included
    using a PCH, so when a PCH is being rebuilt, it might actually get
    reused this way, causing its dependencies to be incomplete afterwards.
    The PCH actually should not be used when being regenerated, but with MSVC
    this apparently happens, even though there's only the option to create
    PCH, not to use it.
