Subject: rec: Set the visibility of FFI functions to 'default' (external)
X-Git-Tag: rec-4.1.2~2^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F6385%2Fhead;p=thirdparty%2Fpdns.git

rec: Set the visibility of FFI functions to 'default' (external)

This makes the symbols usable across shared object boundary (Lua FFI)
even if the default visibility is set to hidden.

(cherry picked from commit 4d9be0eba19ee15ed2b9c45b508086b9fd31d68a)
