[vlc-devel] [PATCH] configure: disable -z defs linker check for OpenBSD.

[Alexandre Janniaux]

Hi,

Sorry for the lack of answers.

Won't this mean that you would allow undefined symbols other
than those from the standard library too? Shouldn't it be
--allow-shlib-undefined instead? Would you have additional
source to add in the commit message for the usage of that
flag?

Regards,
