Ahh, I see.  Yes, it was not a good thing to change gh_new2str that
way.  I'm not sure what to do about this.  Changing this back is just
as bad as the original change from int to size_t.

Personally, I would stop supporting Guile 1.4 and just require Guile
1.6 for newer versions of your code...

I dirty workaround, in this particular case, might be to always pass
NULL as lenp and get the length via scm_string_length (or strlen if
you don't care about '\0' characters in the middle of the string).
