Hmm, I've compiled perl 3.0 on HP 9000 system 300 and 800 HP-UX 7.0 and the
only test that ever failed was that PL13 malloc problem, which was fixed in
PL 15. Since then, no tests has ever failed, including lib.big.

You can compile everything on the 800 series with -O but eval.c and toke.c
will use a LOT of memory and CPU (I did this during the day once, some
users thought the machine had crashed, since they didn't get any response
at all). If you don't have the memory or the swap space you might get
'Out of memory' errors.

On the 300 series you can compile everything except eval.c with -O. 
The register allocation scheme used by the compiler goes into an 
infinite loop on eval.c (as told to me by HP persons).
cmd.c and regcomp.c will give global optimizer warnings.
Compiling toke.c with +O1 will save you a lot of time. Again, depending
on how much memory you have, compiling toke.c may give 'Out of memory' error.
You also need to add +Nw500 (increase switch table stack) to cc.

As for malloc, for 800, use perl:s malloc (PL41), for 300, use -lmalloc or
perl:s malloc.
