I'm recompiling the binutils for the 430X branch on a Win Box. Leaving aside that it takes a couple of hours to reach the first error, I cannot seem to overcome it.
It's either something about deprecated dos to posix path function or a segmentation fault of some sort.. I tried cleaning the workspace and reinstalling the newest version of cygwin (read binutils), to no end. Anybody got a working mspgcc for the 430X microcontrollers? I'm giving up hope and will suggest buying a compiler if I can't make it work until Friday.
