[vlc-devel] [PATCH] configure.ac: enforce compilation check for wordexp

Hello all,

If I recall correctly, in the past we discussed the situation that a symbol might not be available in the oldest OS version we support, but it was introduced later on and is available in the current version we are compiling on.
This is a problem which is specific to release building of VLC, which can be considered a special use case.

Now the situation seems different, because the symbol seems to be not available at all on iOS. Please correct me, but any developer, building for iOS, will now face this problem and cannot build VLC anymore without extra (to be adapted wrapper scripts).

BR. David
