[FFmpeg-devel] [PATCH 2.1/3] libavformat/protocols.c: avio_enum_protocols(): Split declaration and initialization

[Michael Witten]

The main purpose of doing this is to allow for inserting a
a statement label; as I recall, a label cannot be placed
just before a declaration, even when that declaration has
an initializer (then again, I never tried, so maybe this
is not true...)
