/* The cygwin version of sqlite3 has a patch which calls
SetDllDirectory("/usr/bin") on init. It was intended to fix extension
loading, which we don't use, and the effect of SetDllDirectory is
inherited by child processes, and causes libraries to be loaded from
/usr/bin instead of $PATH. This breaks quite a few things (e.g.
checkPhase on openssh), so we set it back to default behaviour. */
