commit 1f5c5624f48b078e8c421874bf0015e84bda57f7 Author: Sebastian Hahn sebastian@torproject.org Date: Fri Jan 20 23:13:35 2012 +0100

Use dead_strip to reduce binary size on OS X

This option seems to be supported all the way back to at least 10.4, so enabling it for OS X in general should be fine. If not, someone will yell.

With no libs statically linked, that's a 3% win in binary size, with just libevent linked statically, this gives us an advantage of 5% in terms of binary size, and with libevent and openssl statically linked, we gain over 18% or over 500KB.
