Uhm, then somethings wrong with the parser. As I said currently the
qmake parser only recognizes NEWLINE tokens, but the example file
contains no newline in the first 3 tokens.
All I'm asking is to get an error message telling me on which token the
error occurs, not the one after that and the error occurs when the
parser expects NEWLINE but gets something different (IDENTIFIER in this
case, while it reports PLUSEQ).
I hope its clear I'm not asking for the last recognized token, I'm
asking to get the last unexpected token.
Beware the one behind you.
