2 # Makefile.legacy - support for backward compatibility
4 # This file contains placeholders to detect backward-compatibility problems.

6 # here that issues an error when the old feature is used.
8 # This file is not included if BR2_DEPRECATED is selected, so it is possible
9 # to bypass the errors (although that's usually a bad idea).
