Subject: init(8): fix signal handler boolean type and qualifier
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=bdce9d03b49cd9b7a0daee512f5ee29e4e23a121;p=openbsd

init(8): fix signal handler boolean type and qualifier

The variable "clang" is modified from a signal handler.  Change it
from an 'int' to a 'sig_atomic_t' and mark it 'volatile', as we
recommend in signal(3).
