Yes, it fixes.
But now the previous MX sync problem on Tru64 UNIX shows up again. Is it possible to apply the previous fflush() patch again? Did this patch brake something on other platform?

Here is the extract from the man page of fopen(3) on Tru64 UNIX:

> When you open a file for update, you can perform both input and output
> operations on the resulting stream. However, an output operation cannot be

So between fprintf and fgets an fflush is required in select_protocol(). (extract of the original code):

                fprintf(stream, "vers%d\n", vers);

                sync_waitdata(s);
                if (fgets(line, LINELEN, stream) == NULL) {

There is on spurious fflush() a bit later that is not really needed.

Bests,
