It is part of the construct the headers use to implement the
CAMLparam... macros.  Strictly it isn't necessary in C++, since you can
have declarations in the middle of a block, but then there would be
different constructs for C and C++.

BTW, what about having a
  (void) caml__dummy_##x;

at the end of the CAMLxparam... macros?  This does shut up the warning,
at least on gcc.
