Thanks; for internal functions the name isn't as important :)

New functions prototypes should go into internal.h, though.
ruby/intern.h ended up being part of the public API and external
libraries depend on it :<

There's no reason for arg_rest_dup to be a macro instead of a
static inline function.  Static inlines are preferred because
they make life easier for the compiler and debugger.

Also, multi-line macros without "do {} while (0)" is dangerous
to control flow.

Thanks again.
