Correct, this patch changes from using the defaults (directory, file and store)
and thus the env variable overrides, to hardcoding the new winstore which came
in 3.2 as the only option.  While I agree that we probably should allow
winstore (and other such stores for other platforms when/if they happen) I
don't think making it the only option is the right way.

AFAIK one cannot change the default store in OpenSSL short of recompiling
OpenSSL.
