+Subject: [PATCH] awk: Prepare for Gawk 5.0.
+
+* src/Makefile.am: Use pkg_namespace (instead of namespace).
+* src/mkerrnos.awk: Likewise.
+* lang/cl/mkerrcodes.awk: Don't escape # in regexp.
+* src/mkerrcodes.awk, src/mkerrcodes1.awk, src/mkerrcodes2.awk: Ditto.
+
+--
+
+In Gawk 5.0, regexp routines are replaced by Gnulib implementation,
+which only allows escaping specific characters.
+
+GnuPG-bug-id: 4459

+Upstream-Status: Backport [https://dev.gnupg.org/T4459]
