private with target-specific variables

[Mario Schwalbe]

Hi,

I'd like to report a bug (or a feature...), I discovered recently:
If the private keyword is used to define a target-specific variable, make
suppresses inheritance, but also tries to build a target `private' as
prerequisite. Using other keywords like export or unexport, work as
documented. The attached makefile reproduces the mentioned effect.

Please also reply to my address as I'm not subscribed to the mailing list.
In case this bug is already known, please ignore this request.

Thanks and ciao,
    Mario Schwalbe
