+ -- but it has other disadvantages.
+ -- -single_module
+ -- Build the dynamic library as a single "module", i.e. no dynamic binding
+ -- nonsense when referring to symbols from within the library. The NCG
+ -- assumes that this option is specified (on i386, at least).
+ -- -Wl,-macosx_version_min -Wl,10.3
+ -- Tell the linker its safe to assume that the library will run on 10.3 or
+ -- later, so that it will not complain about the use of the option
+ -- -undefined dynamic_lookup above.
+ -- -install_name
+ -- Causes the dynamic linker to ignore the DYLD_LIBRARY_PATH when loading
+ -- this lib and instead look for it at its absolute path.
+ -- When installing the .dylibs (see target.mk), we'll change that path to
+ -- point to the place they are installed. Therefore, we won't have to set
+ -- up DYLD_LIBRARY_PATH specifically for ghc.
