Ultrix hints

Ultrix hints

Subject: Re: Perl 5.003_28 is available

The hint file for ULTRIX is out of date with respect to the size
of the Perl_yylex() function.  I found this after enabling -O2,
which works in recent versions of the compiler.  Also, despite
the inability of the standard dist unit to detect the fact, the
ULTRIX dirent struct does too have a d_namelen field.

Patch for that attached.

Also, of course, as expected, ULTRIX still fails t/io/fs.t test
#25, since [f]truncate can't be used to extend a file on that OS.
All other tests are fine.
