Preparing Wine 5.0.1 for GCC 10

[Gerald Pfeifer]

Hi Alexandre,

can you please push the patches to the Wine 5.0 branch for the 5.0.1 
release?  

That'll allow the stable release branch to build on rolling distros
with newer compilers over the coming months/year.

    schedsvc/tests: Fix compilation with recent gcc/clang versions.

    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.
