PR 367/filesystem
* src/dosfs/Makefile.am, src/dosfs/fat.c, src/dosfs/fat.h,
src/dosfs/fat_fat_operations.c, src/dosfs/fat_file.c,
src/dosfs/msdos.h, src/dosfs/msdos_dir.c: Some bugs were still
present in the DOSFS implementation:
- FAT12 did not work properly on Big-Endian machines
- Some synchronization and error handling problems were present
- Some legal codings for EOC were not recognized
