I didn't notice that anywhere.

I agree the use of signal() immediately disturbed me, but I didn't read its implementation. Maybe it does the job. In any case, we could use the occasion to fix that as well and replace signal() with sigaction() in the same patch. -- Richard Braun _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
