Just a note to say that calling `sigprocmask` is _expensive_ and there's no way you want to do it around allocations in general.

There are ways to prevent signals causing re-entry without actually making the system call to `sigprocmask`. I'm not sure what your motivation is, so I can't comment on why you...

Thanks for the very rapid response. Yes, I can confirm that the Authentication Decisions list did have an entry for the site. It did not say "send no cert" but...

I note that you already link some UI elements with ⓘ, e.g.

Checking changes against [Autoconf documentation](https://web.archive.org/web/20240925080748/http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.72/autoconf.html). 3. AC_LANG_C is indeed marked as obsolete in the macro index and removed in https://github.com/Ravenbrook/mps/pull/289/files#diff-49473dca262eeab3b4a43002adb08b4db31020d190caaad1594b47f1d5daa810L28-R28 .
