+To configure `patch' for DJGPP, issue these commands from the
+`patch' source directory:
+
+	pc\djgpp\configure
+	make
+
+To build `patch' in a directory other than where the sources are,
+add a parameter that specifies the source directory, e.g.:
+
+    e:\gnu\patch-2.3\pc\djgpp\configure e:/gnu/patch-2.3
+
+You MUST use forward slashes to specify the source directory.
+
+Running configure.bat requires a port of `sed'.
+You can find one on the usual DJGPP archive sites.
+
+
+Thanks to Eli Zaretskii <eliz@is.elta.co.il> for
+suggestions and ideas for this DJGPP port.
