Many files:
inode.c (ext2fs_open_inode_scan): Initialize the group variables
so that we don't need to call get_next_blockgroup() the first
time around. Saves a bit of time, and prevents us from
needing to assign -1 to current_group (which is an unsigned
value).
icount.c (insert_icount_el): Cast the estimated number of inodes
from a float to an ino_t.
alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c, expanddir.c,
ext2fs.h, fileio.c, freefs.c, get_pathname.c, getsize.c,
icount.c, initialize.c, inline.c, inode.c, irel_ma.c,
ismounted.c, link.c, lookup.c, mkdir.c, namei.c, native.c,
newdir.c, openfs.c, read_bb.c, read_bb_file.c, rs_bitmap.c,
rw_bitmaps.c, swapfs.c, test_io.c, tst_badblocks.c,
tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c, valid_blk.c,
version.c: If EXT2_FLAT_INCLUDES is defined, then assume all
of the ext2-specific header files are in a flat directory.
block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
all assignments from void * to be compatible with C++.
closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
make sure the contents of the disk are flushed to disk.
dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
avoid C++ namespace clash.
bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
avoid C++ namespace clash.
ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
unlink.c: Change private to be priv_data (to avoid C++
namespace clash)
