-# Makefile.in for building crosstool-NG
-# This file serves as source for the ./configure operation
-
-# This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
-# to set additional flags in the current Makfile ( see:
-# http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
-# should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
-# so we have to work it around by calling ourselves back if needed
-
-# So why do we need not to use the built rules and variables? Because we
-# need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
-# and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
-# nor a command associated, and that built-in implicit rule takes precedence
-# over our non-built-in implicit rule '%: %.in', below.
-
-# CT_MAKEFLAGS will be used later, below...
-
-# Do not print directories as we descend into them
-ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)
-CT_MAKEFLAGS += --no-print-directory
-endif
-
-# Use neither builtin rules, nor builtin variables
-# Note: dual test, because if -R and -r are given on the command line
-# (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding
-# '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )
-# Further: quad test because the flags 'rR' and '-rR' can be reordered.

+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
