Subject: use ssp-buffer-size=1 to avoid Werror failures
Commit: 6751899fe1c85ad7fdddc9fea74387098ecab015

Build on Ubuntu 10.04 64-bit was failing:

util.c: In function ‘parse_http_time’:
util.c:1370: error: not protecting function: no buffer at least 8 bytes long

We don't want to lose -Werror, and we don't care too much about the
added overhead of protecting even small buffers, so let's simply turn on
SSP for all buffers.

Thanks to Jacob Appelbaum for the pointer and SwissTorExit for the
original report.
