# Darwin's linker uses:

#	-dylib_file /path/shlib:/path2/shlib
#	-dylib_install_name /path/shlib
#	-install_name /path/shlib
#
# to pass the installed locations for the shared libraries to the
# linker, and we need to pass the extra argument unmodified.  The
# purpose of -seg_addr_table_filename is more obscure, but Darwin's
# imake rules use it.
