# 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' )

 ifeq ($(filter Rr,$(MAKEFLAGS)),)

 ifeq ($(filter -Rr,$(MAKEFLAGS)),)

 CT_MAKEFLAGS += -Rr

 endif # No -Rr

 endif # No Rr

 # Remove any suffix rules
