cannot install gcc-2.95.2 on OSF/1 V3.2

./configure --prefix=/vol/gnu --enable-shared

"make bootstrap" works fine until the end of building stage1:

for name in _eh; \
do \
  echo ${name}; \
  ./xgcc -B/vol/gnu/alpha-dec-osf3.2/bin/ -B./

  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  ar rc tmplibgcc2.a ${name}.o; \
  rm -f ${name}.o; \
done

... and so on

Btw. It doesn't matter if I use gcc-2.8.1 or cc as the bootstrap
compiler.
Also removing "--enable-shared" doesn't prevent the assembler error
messages.
