    [WINESYNC] msi: Properly declare variables in msi/tests/utils.h as extern.
    
    Omitting the extern storage qualifier when declaring a global variable in
    a header file is mistake. If that header is included by several files it
    results in multiple definitions of the same variable (unless -fcommon is
    specified or assumed, the latter being the case for GCC 9.x and earlier).
    
    This fixes building with GCC 10.
