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> * d10v/configure.ac, igen/configure.ac, m68hc11/configure.ac, mips/configure.ac, mn10300/configure.ac, v850/configure.ac: Regenerated, after change to common/aclocal.m4.
