problem compiling gcc 2.95.2 on Dunix4.0f

[Mohamed dot El-Fathaoui at alcatel dot fr]

Hi all
I'm installing gcc 2.95.2 on DUNIX 4.0d with those options:
   configure --prefix=/usr/var/gcc/gcc-bin --enable-threads --enable-shared
That works fine.
   make bootstrap gives this error when compiling:
...
cc  -DIN_GCC -DHAIFA    -g  -DHAVE_CONFIG_H  -o fix-header fix-header.o \
   scan-decls.o scan.o libcpp.a ` case "obstack.o" in ?*) echo obstack.o ;; esac ` ` case "" in ?*) echo  ;; esac ` ` case "" in ?*) echo  ;; esac `  ` case
 "" in ?*) echo  ;; esac ` ` case "" in ?*) echo  ;; esac ` -lmld
if [ -f fixhdr.ready ] ; then \
        true; \
else \
        touch fixhdr.ready; \
fi
Various warnings and error messages from fixproto are normal
if [ -d include ] ; then true; else mkdir include; fi
if [ -f include/fixed ] ; then true; \
else \
  : This line works around a 'make' bug in BSDI 1.1.; \
  FIXPROTO_DEFINES=""; export FIXPROTO_DEFINES; \
  mkinstalldirs="/bin/sh ./mkinstalldirs"; \
    export mkinstalldirs; \
  if [ -d /usr/include ] ; then \
    /bin/sh ./fixproto include include /usr/include; \
  else true; fi; \
  touch include/fixed; \
fi

make terminates with errors
What can I do to overcome this problem?
Any help? thanks
