LDC recognises options starting with "-Wl," and passes them to the gcc
driver rather than prefixing them with -Xlinker. However, this should be
equivalent to just leaving off the -Wl, entirely like in your first
example. Have a look at the linker command line (ldc2/dmd -v) to see
what is going on; there is no magic involved in invoking the linker.
Similarly, you can have the gcc driver display the ld command invoked.
Just as a general hint in case you don't know them already, `otool -L`
and `install_name_tool` are also useful for dealing with shared
libraries on OS X. Also note that D shared libraries are not supported
by DMD on OS X yet, if that is what you are after.
