Void is not a legal argument. The bytecode file uses the void marker as
a way to store the ... for a varargs function. IE, the declaration:
in C, becomes the LLVM type 'void ()*' %foo. The C declaration:
becomes the LLVM type 'void (...)*' %foo, which is stored in the bytecode
file (to be compact) as 'void (void)*'.

That is just 'int ()', function returning int, with no arguments.

Void is not a legal argument type, it is just used as a marker in the
bytecode files. :)
