|

| 91 | # There's a bit of oddness here if you try to use a variable to hold the
|
|---|
| 92 | # prefix character for a define. Even though something like this:
|
|---|
| 93 | #
|
|---|
| 94 | # define foo
|
|---|
| 95 | # echo bar
|
|---|
| 96 | # endef
|
|---|
| 97 | #
|
|---|
| 98 | # all: ; $(V)$(foo)
|
|---|
| 99 | #
|
|---|
| 100 | # (where V=@) can be seen by the user to be obviously different than this:
|
|---|
| 101 | #
|
|---|
| 102 | # define foo
|
|---|
| 103 | # $(V)echo bar
|
|---|
| 104 | # endef

| 105 | #
|
|---|
| 106 | # all: ; $(foo)
|
|---|
| 107 | #
|
|---|
| 108 | # and the user thinks it should behave the same as when the "@" is literal
|
|---|
| 109 | # instead of in a variable, that can't happen because by the time make
|
|---|
| 110 | # expands the variables for the command line and sees it begins with a "@" it
|

| 111 | # can't know anymore whether the prefix character came before the variable
