[FFmpeg-devel] [PATCH] Change broken -Werror=implicit flag in configure into working flag

[Eli Friedman]

Patch attached.  At least with gcc 4.4.3, -Werror=implicit does
nothing, and -Werror=implicit-int does not work with -std=c99.

The configure change exposes an error in ffserver.c, so I patched that
as well; I'm not sure if this is the best fix, though.  The function
in question is ff_url_split.
