    lang/opencoarrays: Fix build with GCC 14

    GCC 14 turns some warnings into errors. Switch them back to warnings by
    adding -fpermissive to CFLAGS.

Fixed.
Comment 3 Gerald Pfeifer freebsd_committer freebsd_triage 2024-12-23 02:42:02 UTC 
Adding -fpermissive is a hack to force a build on software not honoring
a language standard that's three decades old.

IMnsHO any such change should be accompanied by deprecating the respective
port, with a generous EXPIRATION_DATE of four to six months in the future.
