--- Comment #6 from John Marino <gnugcc at marino dot st> --- oh, sorry, you're trying to bisect. Unfortunately this is the first time I tried to build gcc 7.0 in this configuration. My previous builds were for gcc 6 and it's been several months since I ran a test build. I build gcc 7.0-devel all the time as a "port" along with 24,000 other ports, but that version of gcc-7 doesn't include the Ada compiler.
