Subject: [PATCH] libstdc++: more #pragma diagnostic
The CI saw failures on 17_intro/headers/c++2011/parallel_mode.cc due to
-Wdeprecated-declarations warnings in some parallel/ headers.
libstdc++-v3/ChangeLog:
* include/parallel/base.h: Suppress -Wdeprecated-declarations.
* include/parallel/multiseq_selection.h: Likewise.
