* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_copy-file-range): Set to
true to avoid compiling copy-file-range.c on MS-Windows. The
function 'copy_file_range' is not used on MS-Windows, while
compiling the file triggers warnings because lib/unistd.h, where
its prototype is declared, is omitted in the MS-Windows build.
