This reduces the size of every dynamically linked executable by 248 bytes, and it reduces the size of static executables by a lesser amount. It also eliminates some global namespace pollution. With this change in place, the source for dlfcn.h should probably be moved to "/usr/src/include". I'll save that for another day. Compatibility note: Programs which use dlopen, if compiled on systems with this change, will not run on systems with a libc from prior to this change. Very few programs use dlopen, so I think that is OK. Revision Changes Path 1.35 +1 -5 src/lib/csu/i386/Makefile 1.33 +17 -119 src/lib/csu/i386/crt0.c 1.42 +7 -3 src/lib/libc/gen/Makefile.inc
