Re: OpenSSL 1.x support?

I've found the reason. It's caused by using -isystem flag. I've patched
configure script to disable it and was able to successfully build curl with
openssl 1.
In my system, in clang system include directories, there is
/usr/local/include/openssl installed (version OpenSSL 3.1.3 19 Sep 2023).
So, clang was using it instead of the path I provided. Culprit - this
isystem flag.
So, is it curl build script bug? Why is it using this flag?
