4d3db136 seems to be OK on REL_13_STABLE with a direct cherry-pick.
REL_11_STABLE and REL_12_STABLE require two different changes:
- pg_config.h.win32 needs to list OPENSSL_API_COMPAT.
- Solution.pm needs an extra #define OPENSSL_API_COMPAT in
GenerateFiles() whose value can be retrieved from configure.in like in
13~.

Anything I am missing perhaps?
