 ## Resubmission
 This is a resubmission. In this version I have:
 
-* Used the `FCLEN` macro in the extern declaration of `dsyr` and `FCONE` 
-  when calling `dsyr`.
-
+* Used the `FCLEN` macro in the extern declaration of `dsyr` and `dchur` 
+  and `FCONE` in calls afterwards. I have fixed the error I made in the last 
+  submission by doing exactly as stated in WRE as emphasized by Tomas 
+  Kalibera on r-package-devel mailing list at the 3/9.
+* I cannot reproduce an error with gcc 10 which I got mail from Brian Ripley 
+  about with gcc 10.0.0 20191008, Ubuntu 16.04.6, R 3.6.1.
+
 There is a note about the size on most platforms.
