Are you using ruby 1.8 or 1.9? 1.9 makes rb_str_replace non-static and
declares it in intern.h. I don't see it in 1.8's intern.h, so its very
likely static there. If you're on 1.9 I say just go ahead and call it.
If on 1.8, you're looking at calling a static function from the
outside which is difficult and icky at best.

Official policy is that only funcs in ruby.h are considered part of
the public api, and anything else shouldn't be used. Actually obeying
this would mean that such useful and necessary utilities as rb_str_new
and rb_ary_new couldn't be used by extensions, so it has to be taken
with a gain of salt. I think you should be fairly safe with
rb_str_replace. (Tho ruby maintainers are in effect reserving the
right to change its calling conventions without warning or regret, it
is unlikely they will do so.)

Yeah, that's slow. And klutsy. Unfortunately, it is what you have to
do to call a ruby method most of the time :(. If you're on 1.8, this
is probably your best option.

One other option is to fiddle directly with the fields of struct
RString, but I don't recommend that unless you're really dedicated.
