You are right it's defined in opensslconf.h but also even if i add 'shared' to
the Configure command.
This is strange. Btw on Linux it's not even mentioned in opensslconf.h.

I thought as much but i had it in the wrong place.
So i put it before the 2macros as you and it's working great now.

Without this trick it's still doing the stuff in the else part.
I have to figure out why OPENSSL_NO_DYNAMIC_ENGINE is defined in opensslconf.h.
Thank you very much for your help, Victor.
