fixes for hints/svr4 for UnixWare >= 2.1.1

We've just upgraded from UnixWare 2.1 to 2.1.2 (*See footnote).  I was
supprised to see that I got

	d_stdio_cnt_lval='undef'
	d_stdio_ptr_lval='undef'

A quick bit of spelunking showed that in the 2.1->2.1.1 upgrade stdio.h
got modified, the _cnt and _ptr fields in FILE* got renamed to __cnt and
__ptr.

Here's a patch to hints/svr4.sh, all tests pass.
