I have PHP 7.2.9 running at the moment and there was no problem with that installation but it doesn't have imap support installed. I copied the link that you referenced and it is identical to the config.m4 file in the PHP 7.3.0 distribution that I downloaded. From your note I think that you feel that this patch is not complete but I don't know how to check. I am willing to try any suggestions that you might have. ...and thanks very much for the prompt response.
