Problems porting Openssl 1.1.1d to zos.

Dear all,

I stumbled across this mails when looking for information regarding OpenSSL
on zOS. Currently, I am working on getting OpenSSL 1.1.1c running on zOS. So
far I created my own config "target" inside 10-main.conf based on the old
configuration that was used pre OpenSSL 1.1.0.

Still, I was not able to get that far yet and was wondering how you
proceeded regarding this issue? Apart from some github issues and the likes
regarding EBCDIC patches I was unable to find much advice on how to
configure the build and how to tackle common issues. One config target for
zOS OS390 was created a while back but then removed again from OpenSSL
1.1.1. With my config target I made it to the compile step but still face
build issues. Reaching a complete build like Wendell Nichols would already
by a great step.

Are any of you aware of zOS specific OpenSSL development branches that I
have yet to find? Or is this mainly done in private repositories/branches
and not offered for PRs to the OpenSSL repository?

Any advice is greatly appreciated.
