Re: [bug-inetutils] FW: Bug-inetutils post from address@hidden requires approval

Thank you for the bug reports.  Could you try the following patch?
Another user reported similar problems, but I think it was a bit
different platform.

You will need to have autoconf (2.60) and automake (1.9.6) installed
to rebuild the configure script by running ./autogen.sh

        * configure.ac: Check for sighandler_t and __sighandler_t.
        * libinetutils/setsig.c (SIGHANDLER_T): New macro.
        Use it in function declarations.
