Compile Error in Cygwin / openssl 1.1.1d

Georg Höllrigl
Hello,

I'm getting this error on compiling on MobaXTerm (basically Cygwin)
compiling 1.1.1d:

--------------------------------------------------------------------------

I tracked down what has changed. I guess the problems were introduced with
that issue & commit:
https://github.com/openssl/openssl/issues/9385
https://github.com/openssl/openssl/commit/38f6f99cdf0a87345d646d30a764c089c3
8627ad

Replacing the file crypto/dso/dso_dlfcn.c- with the version from 1.1.1c
fixes the problem.

Is there a way to get that fixed otherwise? Is that sufficient for an issue
on GitHub?
Any more Information I should provide?

Kind Regards,
Georg
