Ok, then gnulib will have to use '__base' instead of '_base' on your system.

Good to know.

OK, now we also need the predefines of the other compiler. Can you show
the preprocessing output ("cc -E") of this file:
=======================================================================
#ifdef _SCO_DS
XX_SCO_DS
#endif
#ifdef _SCO_DS_LL
XX_SCO_DS_LL
#endif
#ifdef __OPENSERVER6__
XX__OPENSERVER6__
#endif
#ifdef __UNIXWARE__
XX__UNIXWARE__
#endif
=======================================================================
