+Subject: Patch 7.3.1221
+Fcc: outbox
+From: Bram Moolenaar <Bram@moolenaar.net>
+Mime-Version: 1.0

+
+Patch 7.3.1221
+Problem:    When build flags change "make distclean" run into a configure
+	    error.
+Solution:   When CFLAGS changes delete auto/config.cache.  Also avoid adding
+	    duplicate text to flags.
+Files:	    src/Makefile, src/configure.in, src/auto/configure
