These are 2 unrelated issues, not sure why they are filed together.

For %0b issue see https://github.com/illumos/gcc/pull/19, you can update your sparc gcc 4.4.4 once/if it's accepted.

The trap.c compilation issue is a false positive from unsupported compiler, so I'm not sure we need to do anything here.
