Hm, this looks like there is a problem with the installation of the GCC
C compiler on your machine.

I think the first thing to try is to compile McStas with the standard
HPUX compiler (assuming you have it installed). To do this, compile
McStas again as follows:

    rm -f config.cache
    setenv CC cc
    ./configure --prefix=/user/glhansen
    make

and see if it helps (or mail me the output if it does not). You do not
need superuser privileges to install McStas. Just let me know if you
need further assistance.

I found the following on the Web, which seems to mention a similar
problem:

The following program works for me on an HP-UX 10.20 machine compiled
using g++

#include <iostream.h>
#include <stdlib.h>
#include <pwd.h>

int main(void)
{
  cout << " hello\n";
  return 0;
}

the pwd.h header is included in the stdlib.h file (at least in the HP
version) so you should look in the gcc fixed include files. gcc does
not use the standard system includes, instead it copies them and
changes them to be ANSI c compliant. The sed program for HP 10.20 is
broken and the gcc installation needs either a patched HP sed or the
Gnu version of sed. If not, compilation of programs will fail with
symptoms similar to the above.
