Problem is asm:

asm (".globl start; start: nop");

Semicolon starts a comment.  Labels must start a line on hpux.

Testing a patch with adjusted asm (uses __hpux).

Dave, do you have a patch for this?  I see it on ia64 hpux too.

Something like this works for hppa*-&-hpux* using gas:

------- Comment #5 from sje at cup dot hp dot com  2010-04-14 19:34 -------
I wonder if using 

asm (".globl start");
asm ("start: nop");

Would work for everyone?  I am going to try that on my nightly HP-UX and Linux
runs.

No.  The second asm will add a tab before the label `start'.  Both
the HP and GNU PARISC assemblers require labels to start in column one.

Also, `.global' doesn't work with the HP assembler.  It also doesn't
like a colon at the end of labels.

I think the following would work with most versions of gas:
asm (.global start\nstart: nop");

The problem with the original form was the `;'.  It introduces a comment
on PA.
