[FFmpeg-devel] [PATCH 2/2] configure: allow mixed declarations and code for Objective-C

[Marvin Scholz]

Mixing declarations and code is quite common in Objective-C (as can be
seen by the number of warnings we have for this in Objective-C files)
and forcing to not do it usually results in worse code, with unnecessary
widely scoped variables, which in turn makes variable shadowing and
accidentally using the wrong variable more common and harder to notice.
