# -------------------------
# 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 #6

# TEST #9

# -------
# Test the basics; a "@" internally to the variable applies to only one line.
# A "@" before the variable applies to the entire variable.
