One really big problem with AddDllDirectory is this: While you can add multiple directories to the search path, the order in which these directories are added does not specify a search order. In fact, the order in which the paths are searched is unspecified per MSDN. In Denis example that means, if we add /usr/bin and /my/dir/bin to the DLL search path, Denis case works or it doesn't, and we never know when it will work and when it won't, and we have no way to influence this. Oh boy. Apart from SetDllDirectory and AddDllDirectory, what about this very simple solution in Cygwin: - Don't call SetDllDirectory at all, thus "." is kept in the search path. - In execve, when creating the Windows environment for the child process, check if $PATH is empty. If so, set $PATH to /bin for the child. Or, check if /bin is in $PATH, if not, add it. That would catch both problems, backward compatibility with Denis scenario, as well as the PATH setting in postfix.
