[antlr-interest] ANTLR3 C target and Visual Studio 6

[Iain Young]

That's entirely possible, (I hadn't considered non-VC compilers).
Unfortunately, we have to keep supporting VC6 for now. I can include
this fix in our stuff and link with a slightly modified library etc, but
is there anything in the terms & conditions which says the fix has to go
into the source stream? I don't want to be breaking any license
agreements by doing this...

Your fix looks like it will break things for non VC compilers.  (Also I
have to
wonder how many #ifdefs it is worth to support a nearly ten years old
compiler.)
