Getting closer.  Now it fails with:

/tmp/ccGqBsBb.o(.text+0xa8): In function `force_unwind()':
: undefined reference to `_Unwind_ForcedUnwind'
collect2: ld returned 1 exit status
compiler exited with status 1
output is:
/tmp/ccGqBsBb.o(.text+0xa8): In function `force_unwind()':
: undefined reference to `_Unwind_ForcedUnwind'
collect2: ld returned 1 exit status

FAIL: g++.dg/eh/forced1.C (test for excess errors)

R.
