[vlc-devel] [PATCH] include/vlc_fixups.h: uClibc needs __STDC_FORMAT_MACROS

[Bernd Kuhls]

Fixes compile error with gcc-4.9.3:

  CXX      demux/mkv/libmkv_plugin_la-util.lo
In file included from ../include/vlc_common.h:893:0,
                 from demux/mkv/mkv.hpp:38,
                 from demux/mkv/util.cpp:24:
demux/mkv/util.cpp: In function 'void handle_real_audio(demux_t*, mkv_track_t*, block_t*, mtime_t)':
demux/mkv/util.cpp:192:79: error: expected ')' before 'PRId64'
             msg_Dbg( p_demux, "discard non-key preroll block in track %d at%" PRId64,
                                                                               ^
