 Somehow the '-DCROSS_COMPILE' is not appearing here... So my bet is that
something went wrong with your configure...

 This was seen already in your original message, but this case revealed the
oddity...

 These seem to be related to the stabs debug format. All cross-compilers
should use the 'gstab.h' and the 'stab.def' it includes. The lines 170...
in the 'dbxout.c' say:

--------------------------- clip -------------------------------------
#if defined (USG) || !defined (HAVE_STAB_H) || defined (CROSS_COMPILE)
#include "gstab.h" /* If doing DBX on sysV, use our own stab.h.  */
#else
#include <stab.h>
--------------------------- clip -------------------------------------

 If the 'CROSS_COMPILE' would be defined, as it should, there weren't
problems with the N_BINCL and N_EINCL, because the 'stab.def' has them.
So the configure command you used, seems to be the reason...

 Although you could just add the missing values (N_BINCL, N_EINCL) into
your native '/usr/include/stab.h' (the values can be found in any BSD
or Linux headers), doing a 'make distclean', reconfiguring and rebuilding
is recommended.

 Your expected configure-command should be something like:

  ./configure --build=hppa1.1-hp-hpux10.20 --host=hppa1.1-hp-hpux10.20 \
   --target=m68k-coff

Ie. your build and host systems are the same, 'hppa1.1-hp-hpux10.20',
and your target is 'm68k-coff'...
 
Cheers, Kai
