Why?

The problem I have with the patch is that in the darwin8 timeframe, dwarf was evolving rapidly and being refined, stabs had the productization and the quality.  We know that stabs works well.  dwarf was mostly in and working, but might have quality of implementation issues.  I don't know that enough testing was put into this change to ensure that there are no regressions, so, for example, did you run the gdb testsuite?  Unfortunately, even that, is kinda light.

Also, if we did want to changed it, it should be done in darwin8.h, not here.
