Log Message:
-----------
really can't think of a better way to do this. suggestions? still need to
verify, but different versions of Mac OS X use different debug symbols types
and are not in sync with gdb (i.e., -ggdb3 doesn't work across library
boundaries on 10.4). cheat and call the sw_vers command to get the system
version, used that to test for a debug debug flag type.
