[antlr-interest] antlr 3.4 beta 4 (release candidate)

[Mu Qiao]

I'm not sure if this problem is related to antlr or the c runtime.
I've already fixed the code for the input stream change which Jim
mentioned in another email. But when I compile the generated code, I
get a lot of errors like the following:
libbashLexer.cpp:xxxx:xx: error: '_empty' was not declared in this scope
libbashParser.cpp:xxxx:xx: error: '_empty' was not declared in this scope
And some errors like:
libbashParser.cpp:xxxx:xx: error: 'FOLLOW_set_in_flcomment420' was not
declared in this scope

My C runtime is 3.4-beta4.
