[FFmpeg-devel] [PATCH] configure: Enable -Wno-implicit-const-int-float-conversion if available

[Martin Storsjö]

This silences a lot of compile warnings (around 160 instances at least), when
compiling with Clang.

These warnings look like this:

    libavformat/http.c:176:133: warning: implicit conversion from 'long long' to 'double' changes value from 9223372036854775807 to 9223372036854775808 [-Wimplicit-const-int-float-conversion]
      176 |     { "end_offset", "try to limit the request to bytes preceding this offset", OFFSET(end_off), AV_OPT_TYPE_INT64, { .i64 = 0 }, 0, INT64_MAX, D },
          |     ~                                                                                                                               ^~~~~~~~~
