[antlr-interest] error in antlrv3tree.g: rule ebnf

[Jens Boeykens]

Hello,

rule ebnf is missing two alternatives: ^(o='^' block) and ^(o='!' block).
These are defined in ebnf in ANTLRv3.g but nog 'caught' in ANTLRv3Tree.g
I've added them in my local version and now it works.

*ebnf
  : ^(SYNPRED block) -> ebnf_synpred(synpred={$SYNPRED}, block={$block.st})
  | ^(SYN_SEMPRED block) -> ebnf_synSempred(syn_sempred={$SYN_SEMPRED},
block={$block.st})
  | ^(ebnfSuffix block) -> ebnf_ebnfSuffixblock (ebnfSuffix
={$ebnfSuffix.st}, block = {$block.st})
  | ^(o='^' block) -> ebnf_treeblock(op={$o},block = {$block.st})
  | ^(o='!' block) -> ebnf_treeblock(op={$o},block = {$block.st})
  | block -> ebnf_block(block = {$block.st})
  ;*

Greetz,
Jens
