3242 specified size.
3243
3244 * sim-bits.h, sim-bits.c: Clean up conditionally compiled #if
3245 WITH_TARGET_BITSIZE so that the compilation will fail when an
3246 unsupported bitsize value is defined.

3343 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
3344 into here. Makes insertion into makefiles easier. Also, change
3345 the way that callback.o, gentmap, targ-vals.h, targ-map.c,

3347 individual simulator directories, taking sources from ../common as
3348 necessary. This replaces the merging of libcommon.a into
3349 linsim.a, which was problematic for the WinGDB build process.
