You are welcome.

It seems that mercury_memory_handlers.c expects MR_HAVE_SIGINFO to be set
in a small set of circumstances, as indicated by the #ifs nested inside #ifdef MR_HAVE_SIGINFO,
but configure.ac sets MR_HAVE_SIGINFO in more circumstances than that. It looks like
mercury_memory_handlers.c was not updated when configure.ac was.

Peter, you wrote most of the configure.ac lines that mention MR_HAVE_SIGINFO,
and you also touched them most recently, so could you please have a look at this?

Not by me.

Have Apple fixed the problems that plagued Catalina when it came out? I have held back from
upgrading my iMac partly because of them (and partly because I want to know for sure that
I can switch off Siri permanently).
