No. It was my fault. I'd changed it to size_t, then (mistakenly) back to `int' rather than to `unsigned int'. Now, I too see this warning, even without any -W* or -O option: $ gcc-3.3 -DHAVE_CONFIG_H -I. -I.. -g -c quotearg.c quotearg.c: In function `quotearg_n_options': quotearg.c:586: warning: comparison is always false due to limited range of data type Sorry about the mix-up. I've just confirmed that this warning (from gcc/c-common.c) does not appear to be associated with any command line option. _______________________________________________ bug-gnulib mailing list bug-gnulib@gnu.org http://lists.gnu.org/mailman/listinfo/bug-gnulib
