# -------------------------
# Make sure that prefix characters apply properly to define/endef values.
#
# There's a bit of oddness here if you try to use a variable to hold the
# prefix character for a define. Even though something like this:
#
# define foo
# echo bar
# endef
#
# all: ; $(V)$(foo)
#
# (where V=@) can be seen by the user to be obviously different than this:
#
# define foo
# $(V)echo bar
# endef
#
# all: ; $(foo)
#
# and the user thinks it should behave the same as when the "@" is literal
# instead of in a variable, that can't happen because by the time make
# expands the variables for the command line and sees it begins with a "@" it
# can't know anymore whether the prefix character came before the variable
# reference or was included in the first line of the variable reference.
# TEST #5
# -------
run_make_test('
define FOO
$(V1)echo hello
$(V2)echo world
endef
all: ; @$(FOO)
', '', 'hello
world');
# TEST #6
# -------
run_make_test(undef, 'V1=@ V2=@', 'hello
world');
# TEST #7
# -------
run_make_test('
define FOO
$(V1)echo hello
$(V2)echo world

# -------
run_make_test(undef, 'V2=@', 'echo hello
hello
world');
# TEST #9
# -------
run_make_test(undef, 'V1=@ V2=@', 'hello
world');
# TEST #10
# -------
# Test the basics; a "@" internally to the variable applies to only one line.
# A "@" before the variable applies to the entire variable.
