[bug #29757] Target-specific variables change their flavor

2010-06-25 Thread Vitaly Grechko 

Follow-up Comment #1, bug #29757 (project make):

I think you are wrong. Simple or deferred expansion is connected to operator,
not variable. Variable does not know what way it was assigned. To get what you
want you can use :+= implemented in 'Fastmake' tool. Unfortunately this
operator is not implemented in GNU make yet.

Maybe in some other *make program, but not in GNU make.  To quote
the info pages:

   For the append operator, `+=', the right-hand side is considered
immediate if the variable was previously set as a simple variable
(`:='), and deferred otherwise.


 Variable does not know what way it was assigned.

They do in GNU make.  Note that += isn't standardized.
