+Subject: [PATCH] Adjust for c23 prototype for strchr
+
+in glibc 2.43+ functions like strchr, memchr, strstr
+and friends are now const-preserving macros
+
+That means if you pass a const char *, strchr now returns const char *,
+which breaks older code patterns that assumed char * or wrapped the
+result in compatibility helpers
+
+Upstream-Status: Pending
