# -------------------------
|
|
# 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.
