/*
|
|
* Getting something that works in C and CPP for an arg that may or may
|
|
* not be defined is tricky. Here, if we have "#define CONFIG_LP_BOOGER 1"
|
|
* we match on the placeholder define, insert the "0," for arg1 and generate
|
|
* the triplet (0, 1, 0). Then the last step cherry picks the 2nd arg (a one).
|
|
* When CONFIG_LP_BOOGER is not defined, we generate a (... 1, 0) pair, and when
|
|
* the last step cherry picks the 2nd arg, we get a zero.
