Can RTEMS toolchains be built via crosstool-ng? If so, I'd be tempted to go down that route. I've got lots of patches I need to try to upstream for crosstool-ng, but would be happy to commit them into the MSYS2 crosstool-ng package if you wanted to go that route? > and I am seeing a some interesting > errors when we get to C++'s libsupc++.
