When a normal Block is parsed, duration is initialized to
AV_NOPTS_VALUE.  If it is not changed, then the track's default
duration is used.  But for SimpleBlock, duration is initialized to
0 instead of AV_NOPTS_VALUE.  This is due to the difference in how
EBML_NEST vs EBML_PASS are processed.  Setting duration to 0 leads
eventually to wrongly estimate the frame duration in util.c

When -std=c99 is used, GCC defines __STRICT_ANSI__ to hide non-ANSI
interfaces; on MinGW32, when this macro is defined, some functions that are
part of POSIX but not of Windows APIs are disabled, including strcasecmp().

The normal dependency tracking system disables them just fine.

It is automatically disabled on both mingw and dos due to
the lack of fork.
