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
