+ * Makefile.in: Link all gnat tools with -static-libgcc, since
+ -shared-libgcc is now used by default on some systems (e.g. linux with
+ recent binutils).
+ Remove references to Makefile.prolog/generic, no longer used.

+
+ * prj-makr.adb (Process_Directory): Put file name in canonical case
+ before matching against the patterns.
+ If gnatname has been invoked as <prefix>-gnatname
+ then invoke the compiler as <prefix>-gcc, not just "gcc".

+
+ * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
+ with expansion disabled. The actual subtype is needed among other
+ places when the selected component appears in the context of a loop
+ bound, and denotes a packed array.
+ (Operator_Check): Always use the first subtype in the
+ error message, to avoid the appearance of internal base types.
+ (Transform_Object_Operation): Copy each actual in full
+ to the parameter associations of the constructed call, rather than
+ using the shallow copy mechanism of New_Copy_List. This ensures that
+ the chaining of named associations is done properly.
+ (Complete_Object_Operation): Rewrite node, rather than
+ replacing it, so that we can trace back to the original selected
+ component.
+
+ * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
+ and calls that use object notation, if the called function is not
+ declared in a withed unit, place the elaboration constraint on the
+ unit in the context that makes the function accessible.
+ (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
+ imposes an elaboration constraint between two packages.

+
+ * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
+ views of a private type after handling its private dependents, to
+ maintain proper stack discipline between entry and exit from the
+ package.

+ by '#' instead of six spaces. The format of xsnames.adb was modified
+ in the last update.

+ * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
+ Update comments.

+
+2005-02-09 Sergey Rybin <rybin@adacore.com>
+
+ * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
+ the difference between compact and incompact layout and add the record
+ representation clause to the example illustrating different layouts.
+ Add the description of '-A5' gnatpp option ("align 'AT' keywords in
+ component clauses").

+
+ * gnat_ugn.texi: Fix typos.
+ Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
+ @file.

+ in the generated documentation.
