I'm pretty sure that you don't want to use -traditional.  Also, I
don't think setting DEFS should be necessary.  I've successfully
compiled Octave on a HP-UX 10.20 system by just running

  ./configure
  make
  make install

and making one small bug-fix to the HP header files:

| /usr/include/sys/time.h:337: `extern' can only be specified for objects and functions

I think this is a bug in the HP header files.  The line

  extern struct sigevent;

at line 337 in /usr/include/sys/time.h appears to be incorrect.  I
changed it to

  struct sigevent;

which allows gcc to compile the file.  To be safe, I made a copy of
the file in gcc's private include file directory (normally something
like /usr/local/lib/gcc-lib/ARCH/VERSION/include, where ARCH and
VERSION depend on your system and the version of the compiler you are
using).  You should probably do that too, rather than edit the system
header files directly.
