[MPlayer-cvslog] r25150 - in trunk/dvdread: ifo_print.c ifo_read.c ifo_types.h

Author: nicodvb

New Revision: 25150

Log:
replaced audio_mapping_t and sub_mapping_t with uint16_t and uint32_t
respectively: conditional bitfields don't have the slightest chance
to be cross-platform, thus they are definitively broken.
Fixed the other files to use bitmasks instead of accessing the
previous bitfield members
