Default A new version of make-dfsg has been uploaded to experimental, please test

Hi,

make 3.82 will require some transitions due to backward
incompatibility on GNU-make-specific features. Some bug reports have
already occurred for build issues with make 3.82, such as
http://bugs.debian.org/603759 . Since there are known backward
incompatibilities, make has been uploaded to experimental. NEWS.Debian
has an incompatibility list.

Testing this new version of make will be appreciated.

Thanks for the heads-up. *sigh*, why do they keep doing that ?

Anyway, can you please post the incompatibility list here, if it's not
too long ? The package itself is still in incoming.

Ian.

Never mind, fetched it myself.

make-dfsg (3.82-1) experimental; urgency=low

* New upstream release. A complete list of bugs fixed in this version is
available here: http://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id= 104&set=custom
* WARNING: Future backward-incompatibility!
Wildcards are not documented as returning sorted values, but up to and
including this release the results have been sorted and some makefiles
are apparently depending on that. In the next release of GNU make,
for performance reasons, we may remove that sorting. If your
makefiles require sorted results from wildcard expansions, use the
$(sort ...) function to request it explicitly.
* WARNING: Backward-incompatibility!
The POSIX standard for make was changed in the 2008 version in a
fundamentally incompatible way: make is required to invoke the shell
as if the '-e' flag were provided. Because this would break many
makefiles that have been written to conform to the original text of
the standard, the default behavior of GNU make remains to invoke the
shell with simply '-c'. However, any makefile specifying the .POSIX
special target will follow the new POSIX standard and pass '-e' to the
shell. See also .SHELLFLAGS below.
* WARNING: Backward-incompatibility!
The '$?' variable now contains all prerequisites that caused the
target to be considered out of date, even if they do not exist
(previously only existing targets were provided in $?).
* WARNING: Backward-incompatibility!
As a result of parser enhancements, three backward-compatibility
issues exist: first, a prerequisite containing an "=" cannot be
escaped with a backslash any longer. You must create a variable
containing an "=" and use that variable in the prerequisite. Second,
variable names can no longer contain whitespace, unless you put the
whitespace in a variable and use the variable. Third, in previous
versions of make it was sometimes not flagged as an error for explicit
and pattern targets to appear in the same rule. Now this is always
reported as an error.
* WARNING: Backward-incompatibility!
The pattern-specific variables and pattern rules are now applied in
the shortest stem first order instead of the definition order
(variables and rules with the same stem length are still applied in
the definition order). This produces the usually-desired behavior
where more specific patterns are preferred. To detect this feature
search for 'shortest-stem' in the .FEATURES special variable.
* WARNING: Backward-incompatibility!
The library search behavior has changed to be compatible with the
standard linker behavior. Prior to this version for prerequisites
specified using the -lfoo syntax make first searched for libfoo.so in
the current directory, vpath directories, and system directories. If
that didn't yield a match, make then searched for libfoo.a in these
directories. Starting with this version make searches first for
libfoo.so and then for libfoo.a in each of these directories in order.
* New command line option: --eval=STRING causes STRING to be evaluated
as makefile syntax (akin to using the $(eval ...) function). The
evaluation is performed after all default rules and variables are
defined, but before any makefiles are read.
* New special variable: .RECIPEPREFIX allows you to reset the recipe
introduction character from the default (TAB) to something else. The
first character of this variable value is the new recipe introduction
character. If the variable is set to the empty string, TAB is used
again. It can be set and reset at will; recipes will use the value
active when they were first parsed. To detect this feature check the
value of $(.RECIPEPREFIX).
* New special variable: .SHELLFLAGS allows you to change the options
passed to the shell when it invokes recipes. By default the value
will be "-c" (or "-ec" if .POSIX is set).
* New special target: .ONESHELL instructs make to invoke a single
instance of the shell and provide it with the entire recipe,
regardless of how many lines it contains. As a special feature to
allow more straightforward conversion of makefiles to use .ONESHELL,
any recipe line control characters ('@', '+', or '-') will be removed
from the second and subsequent recipe lines. This happens _only_ if
the SHELL value is deemed to be a standard POSIX-style shell. If not,
then no interior line control characters are removed (as they may be
part of the scripting language used with the alternate SHELL).
* New variable modifier 'private': prefixing a variable assignment with
the modifier 'private' suppresses inheritance of that variable by
prerequisites. This is most useful for target- and pattern-specific
variables.
* New make directive: 'undefine' allows you to undefine a variable so
that it appears as if it was never set. Both $(flavor) and $(origin)
functions will return 'undefined' for such a variable. To detect this
feature search for 'undefine' in the .FEATURES special variable.
* The parser for variable assignments has been enhanced to allow
multiple modifiers ('export', 'override', 'private') on the same line
as variables, including define/endef variables, and in any order.
Also, it is possible to create variables and targets named as these
modifiers.
* The 'define' make directive now allows a variable assignment operator
after the variable name, to allow for simple, conditional, or
appending multi-line variable assignment.
