Dear all, I've committed the attached patch which fixes a portability issue when bootstrapping on Solaris. Discussed and confirmed in the PR by Jonathan for Solaris and regtested by me on x86_64-pc-linux-gnu. https://gcc.gnu.org/g:43816633afd275a9057232a6ebfdc19e441f09ec (Unfortunately the commit message contains Unicode characters that I got by using copy&paste of the error message. I wonder if "git gcc-verify" could have warned me ...) Thanks, Harald
