I like to use --enable-version-specific-runtime-libs because it seems
cleaner and that's the way the Cygwin gcc packages do it.  I also use
--disable-nls since I don't care for those dozens of various message
catalog files for languages I don't speak.

You will also need --enable-sjlj-exceptions if you ever plan to compile
code that could throw an exception inside a stack frame containing
foreign (non-DW2-enabled) compiled code, such as a win32 callback.  This
can be common in win32 GUI applications, but not an issue if you don't
use C++ exceptions and/or you don't write code that could be called from
a win32 callback.  The dwarf2 EH is a lot faster too.
