[Haifux] Intermingled code and declarations and gcc

[Eli Billauer]

Thanks, that's a great idea. Unless someone comes up with some magic 
flag, I'll do that.


Now, please believe me that I wouldn't think about putting declarations 
in the middle of code in my own sources. But obviously some people do, 
and get away with it. And then I want to compile their code.


So there is no point telling me that something is forbidden, when some 
people do it and I get the punishment. ;)
