As a result of parser enhancements, three backward-compatibility issues
exist: first, a prerequisite containing an "=" cannot be escaped with a

- contain whitespace, unless you put the whitespace in a variable and use the

* 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

* 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.
