+* Subject: g77 bug in assign
+*
+* I found some files in the NCAR graphics source code which used to
+* compile with g77 and now don't. All contain the following combination
+* of "save" and "assign". It fails on a Sun running SunOS 4.1.3 and a
+* Sun running SunOS 5.5 (slightly older g77), but compiles on an
+* IBM/RS6000:
+*
+C
+ SUBROUTINE QUICK
+ SAVE
+C
+ ASSIGN 101 TO JUMP
+ 101 Continue
+C
+ RETURN
+ END
+*
+* Everything else in the NCAR distribution compiled, including quite a
+* few C routines.
