Are we really introducing a bunch of duplication between os/mingw32/ and os/mingw32-w64/ ? I didn't see the part that adds the new dir and does all those copies in the patch; where is it? Or have I missed something? Can't we make configure add -D__IM_REALLY_W64_YOU_KNOW to CFLAGS instead? Or come up with a way to point libstd++ to pick up a new mingw32/os_defines_w64.h file instead that does: #include "os_defines.h" // mingw-w64 should use fully-dynamic-string by default #ifndef _GLIBCXX_FULLY_DYNAMIC_STRING #define _GLIBCXX_FULLY_DYNAMIC_STRING 1 #endif -- Pedro Alves
