+Subject: [PATCH] configure.ac: replace K5_AC_INIT with explicit AC_INIT
+
+autoreconf expects configure.ac to contain a literal AC_INIT invocation.
+krb5 currently uses the custom K5_AC_INIT wrapper, which expands to
+AC_INIT but is not recognized by autoreconf's initial sanity check,
+causing configuration to fail with:
+
+  autoreconf: error: configure.ac: AC_INIT not found
+
+Replace K5_AC_INIT([aclocal.m4]) with its explicit expansion:
+AC_INIT(...), AC_CONFIG_SRCDIR([aclocal.m4]), and build_dynobj=no.
+
+This preserves the existing behavior while allowing autoreconf-based
+builds to succeed.
+
+Upstream-Status: Pending
