Comment(by Sebastian):

 Thanks for reminding me about the gzip, I got the following:

 For Linux (note that I didn't manage to compile openssl with -ffunction-
 sections -fdata-sections here, probably because I didn't try hard enough.
 so only zlib and libevent are using that option). This leads to a binary
 that is 150kB smaller when stripped and gzip'd, a space safe of a little
 over 5%.

 For OS X, the -ffunction-sections and -fdata-section options aren't
 necessary, you just add -dead_strip to LDFLAGS. Here I got 150kB in
 savings for the stripped and gzip'd binaries, that's over 10%. All in all,
 I think it's still worth it because it isn't very hard to implement (at
 least on OS X, openssl on linux/windows might be harder. Not sure).

 To answer Jake's question: yes, sure. We should use it for all our
 binaries if we can.
