Wine Gecko compile issues with GCC 10.1+

[Michael Cronenworth]

Hi Jacek,

I'm encountering an internal compiler error when using GCC 10.1 or 10.2 to try and 
build Wine Gecko 2.47.1. Have you seen this already?

In file included from /builddir/build/BUILD/wine-gecko-2.47.1/wine-gecko-2.47.1/widget/windows/WinIMEHandler.cpp:26,
                  from /builddir/build/BUILD/wine-gecko-2.47.1/wine-gecko-2.47.1-x86/widget/windows/Unified_cpp_widget_windows0.cpp:110:
/usr/i686-w64-mingw32/sys-root/mingw/include/cfgmgr32.h: At global scope:
/usr/i686-w64-mingw32/sys-root/mingw/include/cfgmgr32.h:19: internal compiler error: in linemap_compare_locations, at libcpp/line-map.c:1359
    19 |   typedef CONST VOID *PCVOID;
