amiga-gcc compilation problem with ISL

Hi. I'm trying to compile latest amiga-gcc, and i'm getting this kind of errors from gcc compilation:

Sorry. I couldn't find any tickets about ISL in this repo. But the tip you left in the original repo helped. Thank you! Link: https://github.com/bebbo/amiga-gcc/issues/386
