If you have an older pre-C99 system, I've backported a TLS 1.2 library to gcc
versions as early as 2.5 as long as it has 64-bit ints (long long, usually)
and stdarg.h.

As a test, with a suitably agreeable (or confusable) browser, here are
various period browsers visiting modern HTTPS sites through carl, the
included demonstration application which can also act as a TLS proxy. The
proxy is running on the same machine, no tricks! OmniWeb, at least two
flavours of NCSA Mosaic and MacLynx are all demonstrated.
