+
+2001-12-05 Ed Schonberg <schonber@gnat.com>
+
+ * sem_ch12.adb (Instantiate_Package_Body): if instance is a compilation
+ unit, always replace instance node with new body, for ASIS use.
+
+2001-12-05 Vincent Celier <celier@gnat.com>
+
+ * prj-nmsc.adb (Language_Independent_Check): Issue a warning if
+ libraries are not supported and both attributes Library_Name and
+ Library_Dir are specified.
+
+ * prj-proc.adb (Expression): Set location of Result to location of
+ first term.
+
+ * Makefile.in: Add mlib.o, mlib-fil.o, mlib-tgt and mlib-utl to GNATLS.
+ (prj-nmsc is now importing MLib.Tgt)
+
+ * prj-proc.adb: Put the change indicated above that was forgotten.
