It seems to have an issue with character literals:

1: a = %D27-30
       ^
1:5: error: Illegal character '%' - skipping to end of line

2:0: error: Empty rule

3: b = %B01-10
       ^
3:5: error: Illegal character '%' - skipping to end of line

4:0: error: Empty rule

5: c = %XA0-dc
       ^
5:5: error: Illegal character '%' - skipping to end of line

6:0: error: Empty rule

N.B. the perl implementation at http://www.ops.ietf.org/abnf
also has problems with literals using upper-case B,D,X.
