commit r15-11549-gd7d94554df93a17f5a69d69b94408c2e74feb6f4 Author: Pietro Monteiro <[email protected]> Date: Fri Sep 4 21:23:41 2026 -0400 libstdc++: Use static_cast on OpenBSD ctype_base masks Commit r17-3313-g15419a00a29342 fixed the build on newer OpenBSD versions. However, on platforms where char is signed, the mask constants may be implicitly converted to negative values, causing overflow/signedness change warnings. Add static_cast<mask>(...) to make the conversion explicit and silence the warnings. libstdc++-v3/ChangeLog: * config/os/bsd/openbsd/ctype_base.h: Use static_cast when setting the masks.
