This is really odd.
I've got the 4.16.0 tar.gz for libtasn1 and it does not contain any
such _Pragma / deprecation warnings.
The libtasn1 git repo *does* contain these pragmas, but only in the
dev tree for the unreleased 4.17.0 version.
The homebrew-core.git repo recipe for libtasn1 claims to be using
4.16.0 release
https://github.com/Homebrew/homebrew-core/blob/master/Formula/libtasn1.rb
and those tarballs match what i have.
None the less it looks like your 4.16.0 installed version is in fact
a git snapshot. Damned if I understand what homebrew is doing.
None the less, given that these deprecations are in libtasn1 git upstream,
we're going to have to deal with them.
Regards,
Daniel
