This patch tweaks the error message location for missing header files.
Previously these read:
test.c:1:17: fatal error: 404.h: No such file or directory
#include "404.h"
^
compilation terminated.
With this patch, the pertinent string is underlined:
test.c:1:10: fatal error: 404.h: No such file or directory
#include "404.h"
^~~~~~~
compilation terminated.

* sem_prag.ads (Build_Classwide_Expression): new procedure to
build the expression for an inherited classwide condition, and
to validate such expressions when they apply to an inherited
operation that is not overridden.
* sem_prag.adb (Primitives_Mapping): new data structure to
handle the mapping between operations of a root type and the
corresponding overriding operations of a type extension. Used
to construct the expression for an inherited classwide condition.
(Update_Primitives_Mapping): add to Primitives_Mapping the links
between primitive operations of a root type and those of a given
type extension.
(Build_Pragma_Check_Equivalent): use Primitives_Mapping.
* sem_ch6.adb (New_Overloaded_Entity): Remove call to
Collect_Iherited_Class_Wide_Conditions in GNATprove_Mode. This
needs to be done at freeze point of the type.
* freeze.adb (Check_Inherited_Conditions): new procedure to
verify the legality of inherited classwide conditions. In normal
compilation mode the procedure determines whether an inherited
operation needs a wrapper to handle an inherited condition that
differs from the condition of the root type. In SPARK mode
the routine invokes Collect_Inherited_Class_Wide_Conditions to
produce the SPARK version of these inherited conditions.
(Freeze_Record_Type): For a type extension, call
Check_Inherited_Conditions.
