BTW: to make it more easy to discover at make runtime whether the bug has
been fixed in the make version in use, could a proper new entry be added
to .FEATURES? Maybe 'can-have-lazy-variables'? (I know, I suck at choosing
names).
Better again: would you consider the possibility of adding a new kind
of variables (let's call them "lazy"), so that a definition like:
LAZYVAR = val
behaves exactly as:
LAZYVAR = $(override LAZYVAR := val)$(LAZY)
WDYT?

Stefano
