I want to use a different version of druntime and phobos with GDC but I don't want to overwrite the default ones. Instead I want to specifiy a different include directory during compile time. I first thought that -nostdinc is the option I want, but -nostdinc seems to do something different. How does GDC know where to import druntime and phobos from, and how do I overwrite it?
Kind Regards
