2147 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
2148 into here. Makes insertion into makefiles easier. Also, change

2151 individual simulator directories, taking sources from ../common as
2152 necessary. This replaces the merging of libcommon.a into
2153 linsim.a, which was problematic for the WinGDB build process.
