Martin,
I am a co-maintainer of the mikmatch package in Fedora, and was updating it today to use the 1.0.5 release and build against OCaml 4.00.1.
I see in the Git history that there is a post-1.0.5 changeset related to 4.00 compatibility: https://github.com/mjambon/mikmatch/commit/ae5574f7bc99730b73cb493b9cdc3b379...
Do you have an anticipated release date for 1.0.6? If not, is it necessary or worthwhile to include this as a patch in the Fedora package?
Best, - Michael
