+Subject: [PATCH] fix build failure with recent glibc
+
+RT #133184
+
+pp_crypt() directly manipulates a field inside 'struct crypt_data' to work
+around a bug in an ancient glibc version from circa 2002. New glibc
+releases don't have this field so perl fails to compile. Make the hack
+conditional on glibc version.
+
+Stolen from a patch to the Fedora 28 distribution.
