* version.c: Bump for snapshot.
* expmed.c (expand_divmod): Make op1_is_pow2 depend on unsignedp
for negative constants. Promote EXACT_DIV_EXPR to TRUNC_DIV_EXPR
when op1_is_pow2.
* final.c (shorten_branches): During first pass, assume worst
possible alignment for ADDR_VEC and ADDR_VEC_DIFF insns.
* Makefile.in (distclean): Remove various things left around
by running the testsuite.
