The public header files depend on the the autoconf defines
WORDS_BIGENDIAN and HAVE_SYS_TYPES_H, so we add them to ext2_types.h
so that external programs which try to use ext2fs_swap*() will work
correctly on big-endian systems. Fortunately, few if any programs
need to use this libext2's byte-swap functions directly.

Since version 2.50 autoconf fully supports checking sizes of types
(with AC_CHECK_SIZEOF) when cross-compiling. Therefore there is no
need to preset the respective cache variables anymore. The following
patch removes the special case. There is no need to adjust AC_PREREQ
as it's set to 2.50 already.

Some systems don't have the 'dc' command installed, and this causes
configure to print a warning message unnecessarily for a standard
(non-WIP and non-pre) release of e2fsprogs.
It's easy enough to avoid this problem, so let's do it.

Also removed the --enable-dynamic-static configure option.
Unfortunately the usefulness of building e2fsck statically is gone on
all modern distributions, since everything else on the system is built
dynamically these days. In fact on some distributions it is almost
impossible to build programs statically any more.

Fedora and Red Hat puts the devmapper library in different locations
compared to Debian, so we use pkg-config. Unfortunately Debian's
devmapper.pc file is buggy (See Debian Bug #390243), so we have to
work around it.
Historically, e2fsprogs has tried not to depend on pkg-config, since
its answers are so often **wrong** (the Debian bug has been ignored
for over a year), so I'm hoping I'm not going to regret this.

When compiling with dietlibc, sys/syscall.h isn't supported; as of

Add in randomness based on Linux's thread id (gettid) to avoid race

This shouldn't be an issue if /dev/urandom has proper locking and is

On systems where is multi-path storage device is problem with duplicated
filesystems. The solution is select "the best" device. This is possible
by device-mapper library.
Short quotation from RH bugzilla:
With my patch, all dm devices remains in libblkid cache.
Only the top level dm devices are given high priority
and more appropriate node names (i.e. /dev/mapper/*) are used.
For example, if we have linear mapped dm device "ov1" over
dm device "disk1p3" which is multipath mapped to /dev/sdd3 and /dev/sdh3:
# dmsetup.static ls --tree
ov1 (253:5) <-- /dev/mapper/ov1 or /dev/dm-5
`-disk1p3 (253:4) <-- /dev/mapper/disk1p3 or /dev/dm-4
`-disk1 (253:0)
|- (8:112) <-- /dev/sdh
`- (8:48) <-- /dev/sdd
Original version of blkid will show:
# ./orig/blkid -t LABEL=mpdisk1p3 -l
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
With my patch, blkid will show:
# ./deptree/blkid -t LABEL=mpdisk1p3 -l
/dev/mapper/ov1: LABEL="mpdisk1p3" ... TYPE="ext3"
In blkid cache, all devices are listed:
# ./orig/blkid -t LABEL=mpdisk1p3
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdh3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-4: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-5: LABEL="mpdisk1p3" ... TYPE="ext3"
# ./deptree/blkid -t LABEL=mpdisk1p3
