My version just works but I can't update to a newer version for another couple of days. $ uname -a CYGWIN_NT-10.0 eboyd53ent-lt1 2.9.0(0.318/5/3) 2017-09-12 10:18 x86_64 Cygwin > > This also happens in scripts (where I originally encountered the > problem), not just on the command line. > > Directly outputting it (echo `echo "x86_64-pc-cygwin" | sed > 's/-[^-]*$//'`) works fine, it seems to be specifically related to > setting a variable. > > Any suggestions?
