@ -14,31 +14,19 @@ Version 3.81.90
* Compiling GNU make now requires a conforming ISO C 1989 compiler and
standard runtime library.
* The parser for variable assignments has been enhanced to allow multiple
modifiers ('export', 'override', 'private' (see below)) 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.
* 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be considered out of date, even if they do not exist (previously only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 the parser changes, two backward-compatibility issues exist:
As a result of parser enhancements, two 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.
* 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.
* 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.
* 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

that it appears as if it was never set. Both $(flavor) and $(origin)
functions will return 'undefined' for such a variable. To detect this
