# 1: Simple verification that private variables are not inherited

a:
F = g
a: F = a
b: private F = b

a: b

# 2: Again, but this time we start with "b" so "a"'s variable is not in scope
&run_make_test(undef, 'b', "c: F=g\nb: F=b\n");

# 3: Verification with pattern-specific variables
&run_make_test('
t.a:

F1 = g

%.a: private F1 = a

# 5: Multiple conditions on the same variable.  Test export.
delete $ENV{'_X'};

# 6: Test override.

# 7: Ensure keywords still work as targets
