I agree. But there should be a way to compile gnulib without calling the 
forbidden/old/deprecated API's. That's currently not possible. For example in 
stat-w32.c the "_GL_WINDOWS_STAT_INODES == 2" mode is not enabled yet. And even 
then it would still do a call GetFileInformationByHandle() which will not link 
in the end. (in mingw-w64 it will because they don't builds libs for 
UWP/not-UWP)
