Address the theoretical problem of two threads trying to format a
different unknown error code by using TLS.

On 64-bit systems (or anything with sizeof(long) > sizeof(int)), we
sometimes get error codes passed to error_message which have been cast
from an (int) to an (unsigned int). This almost always happens if
you're using libgssapi_krb5, which returns an error code which is less
than 0 but is returned in an (unsigned int).
For example, -1765328377L gets cast to 2529638919, which is
0x96c73a07, not 0xffffffff96c73a07, so error_message() fails to find a
matching error table.
When error_message() then calls the error_table_name() function to get a
name to use in the "unknown code" message, it gets a correct value back.
This happens because error_table_name() drops most of the higher bits of
the parameter it's passed before doing anything else with it (& 077777777f,
or & 0xffffff). If we did the same thing in error_message(), we wouldn't
have a problem there, either.

Fix the info-dir line so that the menu name does not contain a .info
prefix. First of all, it's ugly, secondly, it causes the install-info
command to fail to remove the com_err info file from the
/usr/share/info/dir file when the comerr-dev package is removed and
purged.

If the environment variable COMERR_DEBUG is set to 1, print out debugging
messages as error tables are added and removed from the com_err library.
If the COMERR_DEBUG_FILE environment variable is set (and the process is
not setuid) the debugging messages may be redirected to a file.

Add a dependency to make sure that the subdirectories are created before
creating all of the object files.

that we won't fail even for error tables created using old
versions of compile_et. Thanks to Nalin Dahyabhai for
this suggested patch.

old library calls initialize_xxx_error_table, and another
library/application calls add_error_table() on the same
error table, and then calls remove_error_table().

necessary. Also fixes a potential SMP/Parallel build problem when one
make process runs compile_et to generate the .h file, and a partially

Update Makefile dependencies.
Update "make depend" production so that it filters out comments
inserted by newer gcc compilers.
Remove sync from e2fsck's "make all" target.
Declare comerr-dev as replacing << e2fslibs-dev 1.33-2, to avoid
errors when upgrading to the new versions of comerr-dev and
e2fslibs-dev
Declare init_error_table as taking a long for the second argument.
Add support for OV-style continuation (closes Debian bug #191900).
Move /usr/include/com_err.h from the e2fslibs-dev package to the
comerr-dev package. (closes Debian bug #191899)

Add a --build-tree option to compile_et to make sure that it uses

Remove legacy support for varargs.h, K&R C, and pre-POSIX signal
