Subject: Since PuTTY depends on lots of features of System 7, have it bale out if
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/56ed4cf7fdc391717c35bd1d71520daaff01eb1b

Since PuTTY depends on lots of features of System 7, have it bale out if
it finds itself running on anything older.  This is better than killing the
whole system with an umimplemented trap.
