* Compiling GNU make now requires a conforming ISO C 1989 compiler and
standard runtime library.
* 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.

fundamentally incompatible way: make is required to invoke the shell as if

* 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.

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,

* 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 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.

* scripts/targets/POSIX: Compatibility issues with Solaris (and
Tru64?); "false" returns different exit codes, and set -x shows
output with extra whitespace. Run the commands by hand first to
find out what the real shell would do, then compare what make does.
