[Shally] why are we passing ** here, compress_zlib() input rte_comp_xform*, this will cause a bug here. So, in call to decompress_zlib() below.

>+	"opportunity for showing off her knowledge, as there was no one to\n"
>+	"listen to her, still it was good practice to say it over) `--yes,\n"

>+	"  Presently she began again.  `I wonder if I shall fall right\n"

>+	"time, as it didn't sound at all the right word) `--but I shall\n"
>+	"have to ask them what the name of the country is, you know.\n"
>+	"Please, Ma'am, is this New Zealand or Australia?' (and she tried\n"
