patch file for 0.9_1 -> 1.0 upgrade
I'll take this one
There is no need to add [MAINTAINER] or [MAINTAINER-UPDATE] in the subject. It clutters the PR database.
Also, you can add the maintainer-approval flag for the patch :)
Sorry... I just follow the porter's handbook, and it says " If the submitter is also maintaining the port, be sure to put [MAINTAINER] at the beginning of the Summary line." 
Maybe it needs some updating?
Anyways, thanks for working on this and telling me about the flag.

You're actually right about the doc. I've seen MAINTAINER in disuse lately, but it's not big deal anyway :)
I don't have any ARM devices to test this port on. Can you confirm this builds in ARM too?
(In reply to Fernando Apesteguía from comment #5)
To my knowledge it does. I did build it on a raspberry pi and also on an arm64 version of FreeBSD. The results are even available as prebuilds, here: http://www.dyncall.org/download
Both where done on FreeBSD 11, though.
