Subject: [newlib-cygwin] Cygwin: update C++ dialect to gnu++14
Date: Sat, 30 May 2020 17:42:01 +0000 (GMT) [thread overview]
Message-ID: <20200530174201.915823858D35@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=d6242d87336d7f06691d1e1d9a3ce9324fd9903c
commit d6242d87336d7f06691d1e1d9a3ce9324fd9903c
Author: Corinna Vinschen <corinna@vinschen.de>
Date: Sat May 30 19:41:18 2020 +0200
Cygwin: update C++ dialect to gnu++14
Disable -std option since gnu++14 is default anyway, but keep
it available as comment.
Update dynamic exception specifications deprecated with
C++11 to C++11-introduced noexcept expression.
