Ah no, as cabal builds into a different directory, dist/build/..., it 
would not take the Lexer.hs file from there, I guess.

Could it be that you have different version of alex somewhere which is 
mysteriously invoked by cabal?  There is something weird about the error

src/full/Agda/Syntax/Parser/Lexer.x:0:2:
     lexical error at character '\n'

If I introduce an error (like a ^G) in the first character of Lexer.x, 
alex-3.1.3 reports

Lexer.x:1:1: lexical error at '\a'

So, alex does not seem to know a line number 0, (at least not in the 
newer versions).
