    > ../../../../../winsup/utils/mingw/cygcheck.cc: In function 'void dump=
_sysinfo()':
    > ../../../../../winsup/utils/mingw/cygcheck.cc:1716:11: error: variabl=
e 'count_path_items' set but not used [-Werror=3Dunused-but-set-variable=3D]
   =20
    As far as I can tell, the value of count_path_items we compute has never
    been used.
