On Solaris setbuf() will discard any pending output to the stream, so
make we call fflush() before calling setbuf().

Solaris's header files are very picky about which C compiler can be
used for SUSv3 conformance. Use of C99 is not compatible with SUSv2
(_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3
(_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently
use SUSv3 so that e2fsprogs will build on Solaris using c99.

Gcc only supports __builtin_expect for gcc versions 2.96 and up.
Since it's tricky to check for gcc 2.95 vs 2.96 (and either are only
used on really ancient systems anyway), we only use this optimization
on 3.x and newer versions of gcc.

E2fsck could to do more damage to a filesystem by trying to relocate
inode tables due to corrupted block group descriptors, and the
relocation could seriously damage the filesystem.
This patch enhances ext2fs_check_desk() so it detects more
self-inconsistent block group descriptors, including the cases where
e2sck might be tempted to relocate the inode table, and reports the
block group descriptors as invalid; this will cause e2fsck to attempt
to use the backup superblocks, which hopefully have not been trashed.

The Hurd only supports filesystems with a blocksize of 4096 bytes, and
128 byte inodes. It also doesn't understand the journal. So force
the defaults to be something which the Hurd can handle if "-o hurd" is
specified on the command line.

The blkid/tests contains new tests for swap, but the type-1 swapfile
test depends on mkswap supporting the "-U" option to specify the UUID.
This is not available even on relatively recent versions of mkswap
(2.13.1 16-Jan-2008) so the test needs to be changed to handle this.
If the "-U" option is not supported, don't verify the UUID in the blkid
output during testing.

Inode 49154, i_size is 14680064000000, should be 0. Fix<y>?
is a bit unexpected. It's because the size is being checked against
the max sizes for bitmap files, not extent-based files.
Nick saw this with his 14TB file.
Patch below applies different size limits to the different file

Print a message when mke2fs uses a default blocksize from an external
journal device, and print a more self-explanatory message so that if
that blocksize is used and ext2fs_get_device_size() returns EFBIG, the
user has a better chance of understanding why mke2fs issued that error
message.

If creating a an external journal via "mke2fs -O journal_dev",
override the fs_type list (i.e., "ext2", "small"), and replace it with
an fs_type list of "journal". This will prevent external journals
smaller than 512MB from being created with a block size of 1k, which
is not very useful and leads to much confusion.

extent.c should only try to include ss/ssh.h when it is compiled with

The syntax for /etc/adduser.conf allows spaces around the equals sign,
i.e.:
GROUPHOMES = no
We were previously asking /bin/sh to source the file, which doesn't
support the above syntax. So pull out the necessary fields via
sed/grep.
