Visual C++ 6 doesn't support variable size arrays on the stack and things
like

FLAC__byte buffer[FLAC__STREAM_METADATA_VORBIS_COMMENT_ENTRY_LENGTH_LEN /
8];

are variable size, because the length is extern const. Using _alloca,
however, works, for example

FLAC__byte*buffer=_alloca(entry_length_len);
