## path creation #########################
# Make the destination directory if neccessary.  For some
# make engines we must do this outside the rule or they
# get confused by the apparent way in which different rules
# can create a particular directory and they infer some kind
# of dependency.

# Makepath. Copyright (C) 2008 Symbian Software Ltd.
# buffering with repeat prevention, makes directories after every 30 calls. Any more might overload 
# the createprocess limit on arguments.
#
# makepathLIST is initialised in globals.mk
define makepath_single
$(if $(findstring $1,$(makepathLIST)),,$(eval makepathLIST:=$(makepathLIST) $1))

# The following turns out to be extremely slow - something to do with using eval 
# or to do with creating huge numbers of TARGET_ variables? BTW, this is an attempt
# to not make things that we have already made.
# define makepath
# $(info makepath_start)$(foreach DIR,$1,$(if $(TARGET_$(1)),,$(call makepath_single,$(DIR))$(eval TARGET_$(1):=1)))$(info makepath_end)

# In general, makepath creates directories during FLM evaluation.
# However, if the WHAT target is being processed then it should do nothing.
