sim/common/ChangeLog:
2005-02-28 Jim Blandy <jimb@redhat.com>
* aclocal.m4 (SIM_AC_OPTION_WARNINGS): Don't include
-Wuninitialized in the default list of build warnings if CFLAGS is
set, and doesn't include -O. (Using -Wuninitialized without
optimization produces a warning, which interferes with compilation
with -Werror.)
sim/ChangeLog:
2005-02-28 Jim Blandy <jimb@redhat.com>

mips/configure.ac, mn10300/configure.ac, v850/configure.ac:
Regenerated, after change to common/aclocal.m4.
