I guess this is considered good enough in practice, although I also don't like this use of strncmp.

I don't have the time to push this though, sorry. -- Jean Delvare _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
