-# Makefile.correct_output_files_for_.S_files.patch
-#
-# The used version of Automake might emit rules that don't put compiled (pre
-# processed) Assembler files where they belong.  We're bitten by this bug
-# because we use the Automake option `subdir-objects', to not clutter the main
-# build directory with all the object files.  The problem is that the emitted
-# rules will place those in the main build directory, but later, when creating
-# the libraries, look for them in the subdirectories.
-#
-# See <http://sourceware.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=automake&pr=492>.
-#
-# Another note: even with versions of Automake that don't have this issue
-# fixed, a correct rule is emitted for linux/src/arch/i386/lib/semaphore.S, see
-# the comment by Thomas Schwinge on 2006-10-10 on the above bug report.
-#
-# Again, a real patch is being used here and not some `sed' magic, so that
-# it'll fail loudly in case some internals we're relying on are changed.
-#
-# TODO.  Remove this block as soon as we don't want to support such legacy
-# versions of Automake anymore.
