Technically that is what it does, except for setting the USE_*RANDOM variables for non-OpenSSL builds. We could skip that too, which I think is what you're proposing, but it seems to me that we'll end up with another set of entangled logic in pg_strong_random if we do since there then needs to be precedence in checking (one might be on Windows with OpenSSL for example, where OpenSSL > Windows API). > -elif test x"$USE_WIN32_RANDOM" = x"1" ; then > +elif test x"$PORTANME" = x"win32" ; then > Typo here, s/PORTANME/PORTNAME. Fixed. cheers ./daniel
