interrupting subjobs does not work on Solaris 9

interrupting subjobs does not work on Solaris 9

[Andrew Maguire]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.3.7.1 (sparc-sun-solaris2.5.1, X toolkit)
 of Fri Apr 23 1999 on uranium
configured using `configure  --x-includes=/usr/openwin/include --x-libraries=/usr/openwin/lib --libexecdir=/usr/local/lib --infodir=/usr/local/share/info'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

If you start a subprocess eg a shell and then start a program e.g,
sleep 20. On Solaris 9 you cannot interrupt the sleep command by use of
C-c C-c.
Now I have tried using this executable on a Solaris 8 machine with no
problem. I have also tried building emacs 20.7 using gcc 2.7 on
a solaris 7 machine and running this executable on a Solaris 9 machine
also exhibits the bug.

I have tried to build emacs20.7 and emacs 21.2 on the Solaris 9 machine
with gcc 3.1 as obtained from www.sunfreeware.com
but I could not compile it because of some header conflicts..

The error reported for building 20.7 on Solaris 9 is:

Re: interrupting subjobs does not work on Solaris 9

[Richard Stallman]

    If you start a subprocess eg a shell and then start a program e.g,
    sleep 20. On Solaris 9 you cannot interrupt the sleep command by use of
    C-c C-c.

This and the other problem need to be investigated by people
familiar with Solaris.  I suspect this one relates to the system calls
used in process_send_signal to send the signal to the subprocess,
or to the use of process groups.
