Thanks a lot. I didn't know about rb_eval_string_protect().

Now, going back to redirecting the output; the source code is full of
printf()'s, fprintf(stderr,...)'s and  puts(). For redirecting the output
elsewhere I'll need to change most of those functions, if not all.

I created a series of macros and functions to use in place of printf and the
like. They're not a great thing, but can be useful. I ask the Ruby
development team to take a look at them and consider including them in a
future release of Ruby, as that might help with the integration of ruby when
embedding it.

There should be no portability problems.

Please let me know what you think about this.
