Hi Ivan, thanks for the report! Your patch puts new logic directly
after an AC_MSG_ERROR() call, so any effect has to come from the fact
that we're no longer restoring the old compiler and linker flags.
That's not what we want -- Curl needs to be isolated from the rest of
the build.

Let's focus on the error you're seeing:

What's your configure line? You need to make sure that your custom
libcurl is used at configure-time, compile-time, and run-time.

And which binaries are complaining? The only thing that should ever be
linked against libcurl is libpq-oauth-18.so.

Thanks,
