Is there a recommended approach to get your
standard configure based unix software to build
against libSystem.B_debug.dylib instead of libSystem.B.dylib?
I am trying to set breakpoints in the system unwinder in
order to debug some bad unwind information being issued in
ecj1 of FSF gcc's libjava support. Is there a best practices
causing the debug system libs to be linked in via configure?

ps Unless I am confused, it seems that one has to build
everything against libSystem.B_debug.dylib (including
shared libraries) in order to set the breakpoints in
the unwinder (ie just linking the main ecj1 program
and not libgcj, etc against libSystem.B_debug.dylib
seems to be insufficient for gdb to successfully set
breakpoints on __Unwind_RaiseException in darwin10.
