# On Darwin (Mac OS X), dwarf2 debugging uses debug info left in .o files,

# so instead of deleting .o files after repacking them into a dylib, we make

# symlinks back to the originals. The symlinks are a no-op for stabs debugging,

# so no need to conditionalize on OS version or debugging format.
