This file is actually used.

Googling on the filename turns up an explanation:

  http://sources.redhat.com/ml/gdb-patches/2004-02/msg00783.html

The actual usage point is in the gnatmake command.
Here's an excerpt from gdb.log:

  Executing on host: gnatmake null_record.adb -P/tmp/migbat-testgdb-VZzpSUK2/test/gdb.ada/gnat_ada -gdwarf-2 -g2 -lm -o /tmp/migbat-testgdb-VZzpSUK2/test/gdb.ada/null_record (timeout = 300)

The "-P/blah/gdb.ada/gnat_ada" switch reads the file gnat_ada.gpr
from the build directory.  The "gpr" stands for "gnat project".

$BUILD/gnat_ada.gpr.in is made from $SOURCE/gnat_ada.gpr by
the usual autoconf magic.  Search for "gnat_ada.gpr" in the
gdb/testsuite/configure.

And the name has to be foo.gpr.in with the ".gpr" for the
"gnatmake -P" to work and the ".in" for the autoconfigury.

I'm pretty clueless about Ada but I think that's what's going on;
corrections welcomed.
