Here are my testing results (with the LIB_DL fix):

* On some machines, I had to install the packages with the <openssl/*>
  header files first:

  - Debian 12:
    # apt install libssl-dev
  - openSUSE 15.5:
    YaST software > install libopenssl-3-devel
  - Slackware 15:
    Download and unpack the openssl-1.1.1w binary packages
  - Alpine Linux 3.19:
    # apk add openssl openssl-dev

* On some platforms, the configure test gave

     checking whether openssl is GPL compatible... no

  due to the <openssl/*> header files being absent:

    - Guix 1.4
    - macOS 12.5
    - Cygwin 2.9.0

* On some platforms, the configure test gave

     checking whether openssl is GPL compatible... no

  because the openssl version is not >= 3.

    - Slackware 15 (has libcrypto.so.1.1)
    - NetBSD 9.3 (has libcrypto.so.14)
    - OpenBSD 7.4 (has libcrypto.so.52.0)
    - Solaris 11.4 (has libcrypto.so.1.0.0)

* On these platforms, the configure test gave

     checking whether openssl is GPL compatible... yes

  and LIBCRYPTO_SONAME got defined.

    - Debian 12
    - Ubuntu 22.04
    - openSUSE 15.5
    - CentOS Stream 9
    - Alpine Linux 3.19
    - FreeBSD 14.0
    - Android

  The value of LIBCRYPTO_SONAME is
    "libcrypto.so.30" on Android,
    "libcrypto.so.3" on the other platforms.
