Side note: I'm not convinced that we will reliably catch a compiler version change in our dependency analysis, so it's probably best to "make clean" between switching compilers to make sure that you don't have old object files with the old compiler. > But the MCORE2 was consistent for several people - including you. > Until this point. .. and our build infrastructure definitely _should_ catch compiler switch changes automatically and force a re-build.
