[Ashok Kumar Sarode]

Hello OpenSSL users,
I need help on following errors which I am getting from myWindows machine building on Visual Studio 2019,
Version 16.11.17.

NOTE: I have re-named file openssl\configuration.h.in to openssl\configuration.hLikewise i re-named err.h, ssl.h, opensslv.h, crypto.h
I downloaded OpenSLL source from GitHub - openssl/openssl: TLS/SSL and crypto library
