# Macros to assist in the handling of paths with spaces

#	encodepath - Uses spacealt, uses /, space-sep-list

#		     Used to conatins lists of paths that may contain

#		     spaces. Used for INCLUDE and LIB paths

#

#	decodepath - Decodes an encoded path-list.

#		     User specifies the item prefix and suffix.

#		     Return list uses \ and may have spaces in pathnames

#	             Prefix items with 1st-arg

#                    Join items with 2nd arg

#

# Usage:

#	aa = $(call encodepath,c:\Program Files)

#	$(call decodepath,-I,;,$(aa))

#  Macros to convert relative to absolute paths

#

#   Work around for a bug in make 3.81 where abspath assumes that the input

#   is a relative path. The work around checks for paths that have a : or start

#   with a '/ - and assumes these are absolute.

#   It will only call makes 'abspath' for relative paths.

myabspath = $(foreach dir,$1,$(call myabs1path,$(dir)))

myabs1path = $(if $(or $(findstring :,$1),$(filter /%,$1)),$1,$(abspath $1))
