 332         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
 333         (SIM_AC_OUTPUT): To here.
 334

 347         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
 348         targ-map.o, and run are built.  They are now built in the
 349         individual simulator directories, taking sources from ../common as
 350         necessary.  This replaces the merging of libcommon.a into
 351         linsim.a, which was problematic for the WinGDB build process.
 352         * run.c:  Include config.h from . instead of ../common.
 353         * Make-common.in:  Remove.  It's no longer necessary.
