branch: master
commit 1cefad6a53979a5d7c7c5158678e2ba2a747ea0e

    Fix LMI_WX_CHILD_DOCUMENT definition to fix g++11 C++20 build
    
    Combining elements of two different enums, such as wxDOC_SILENT and
    LMI_WX_CHILD_DOCUMENT, is not allowed in C++20 and g++11 warns about it.
    
    Avoid this warning simply by not making LMI_WX_CHILD_DOCUMENT an enum
    element at all but long, which is the type actually used by wxWidgets
    for the "flags" parameter.
