Subject: Fix SIGUSR1 handling on Solaris.
X-Git-Tag: v0.3.0~59^2~2
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=02f5def4490f7e12987b0cf77989d42045627df5;p=paraslash.git

Fix SIGUSR1 handling on Solaris.

para_client dies the second time it receives SIGUSR1, because the signal action
is restored to the default state once the signal handler has been called.
