> sorry for breaking your Newlib configuration.

(A point I tried to make was that it wasn't just "mine", but
most "*-elf" ones.  A "real" CI bot for a stable *-elf
simulator target with newlib, gcc, binutils, updating only
each at a time would be nice, and JFTR, no I don't consider
mine "real".)

Aha; yes it works; I regtested gcc for cris-elf as with my
patch.  Thanks for attending to this.  I hope the other
points I raised in my submission will eventually be handled.

Ok, I see, thanks for clarifying.

Thanks; FWIW, I don't have a strong opinion about that.  As
long as it still works, I'm happy.  (Not actually using
newlib for production here, AFAIK.)
