Subject Re: FreeBSD version check for thread-safe sendfile
Date Thu, 11 Jan 2001 20:15:02 GMT
One of the reasons that I was advocating using the globbing feature of
"case" was to avoid the nasty sed expression.

Just do:

  case "`uname -r`" in
      3.4*)
          disable-threads
          ;;
  esac


Cheers,
-g
