How about under zsh/CONSOLE?

Well, if your environment is inconsistent and needs to be rebased, then
all bets are off as to correct behaviour.

Gee, I can make it happen just fine:

For example,
$ cd /bin
$ mv cygcrypto-0.9.8.dll cygcrypto-0.9.8.NOT
$ ./openssl

I get a dialog box popup which says
[openssl.exe - Unable to locate DLL]
"The dynamic link library cygcrypto-0.9.8.dll could not be found in the
specified path"

"Works"(?) for zsh & rxvt, zsh & CONSOLE, bash & rxvt, and, bash & CONSOLE.
