[boost] Program options auto-link bug

From: John Maddock (john_at_[hidden])

The program options library currently doesn't select the dll-import library 
when auto-linking to the dll build of the library - it always tries to link 
to the static lib.  The following patch fixes the issue:

$ cvs diff -u boost/program_options/config.hpp

 // Set the name of our library, this will get undef'ed by auto_link.hpp
 // once it's done with it:
 #define BOOST_LIB_NAME boost_program_options
+// tell the auto-link code to select a dll when required:
+#if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_PROGRAM_OPTIONS_DYN_LINK)
+#  define BOOST_DYN_LINK
+#endif

 // And include the header that does the work:
 #include <boost/config/auto_link.hpp>

OK to commit?
