This is the culprit:

da949cdc lily/lexer.ll (Keith OHara        2011-08-10 00:57:44 -0700 651)
-{UNSIGNED}     | // backup rule

commit da949cdcede0ffb559e9e5e2adbae2088ba1f6d6
Author: Keith OHara <address@hidden>
Date:   Wed Aug 10 00:57:44 2011 -0700

    lexer.ll: remove unused patterns, avoid backing up


It turns all literal negative integers into floating point numbers.
I'll investigate how to do a proper fix.
