Ah, I found my IRC log; apparently it was the `expr match` part: 1635762461 31<egallager>30 hm, looks like I need to use gexpr instead of just-plain expr T 1635762474 31<egallager>30 I guess it's a GNU vs. BSD thing T 1635762672 31<egallager>30 so I guess that's a separate bug to file T 1635762691 31<egallager>30 I guess the g:hash syntax will do for now for the other one I was filing T 1635762767 18<iains> yes, there are some non-portable parts in the customisation … T 1635762803 18<jakub> expr is used twice there, is the problem with expr match or with expr x - y T 1635762865 18* iains thought the initial problem was with the match .. but ICBW T 1635762967 18<jakub> I guess it can be replaced with echo | grep -q too, but for bash that is unnecessary slowdown...; perhaps gcc-git-customization.sh could check if expr match works and if not, use something different... T 1635763046 31<egallager>30 I think it's the expr match part
