They probably fail to address the fixincludes issues that cause you to
run into these problems.

I just happen to work for the company where this port was developed.
I was in no way involved with it, so I'll refrain from commenting on
it.  But I'd expect it to just work, if it's indeed targeted for HP-UX
11, not some earlier version of HP-UX.

Oh, yeah, that problem!  There's a work-around in place for GCC
3.0.1.  The patch is:

2001-07-21  Michael Chastain  <chastain@redhat.com>

	* ltconfig: Set max_cmd_len to a maximum of 512Kb, as it seems some
	HPUX 11.0 systems have trouble with 1MB.  Mark as gcc-local.
	* ltmain.sh: Mark as gcc-local.

Basically, all you have to do is to replace `18' with `17' in
ltconfig, in a line that looks like:

          new_result=`expr "X$testring" : ".*" 2>&1` &&
          lt_cv_sys_max_cmd_len=$new_result &&
-         test $i != 18
+         test $i != 17
  do
    i=`expr $i + 1`
