According to the FDIS [stmt.ambig], these are to be parsed as a
declarations, not function calls. The first declares an object named
`kala', initialized with two arguments, which turns out to be invalid
because it has type void, but disambiguation is syntactic. The second
declares a function named kala2, that takes an empty list of arguments
and returns void.

IMHO, these should also be considered declarations, but egcs considers
these function invocations. The first should be an invalid
definition of an object `kala' in the global namespace, while the
second would be a valid redeclaration of global function `kala2'.
