Well, this line of argument also leads to the suggestion that we should
define a nice stable interface for it to use. I haven't researched it in
depth but if, as it appears, this is a real library used by real Linux apps to
do a real job, and it is our goal to make those apps "just recompile and work"
on Cygwin as they do on Linux, then we should give serious consideration to
supporting libsigsegv and making what it wants to do possible for it.
