Duke3D: Parsing for negated CON labels does not work properly
While it is currently possible to negate gamevars (and constant integers) inside CON statements as such:
mul temp1 -temp2
The same is not possible for labels. The following code will throw a warning in the console, indicating that the label is being interpreted as a constant due to the negation that's placed in front:
define TEST 10
var temp 20 0
onevent EVENT_ALTFIRE
set temp -TEST
al temp
endevent
Console output after pressing Altfire:
CONLOGVAR: L=6 temp (Global) =0
Not only does the parsing fail, it also produces a completely unexpected value.
