# Makefile include fragment to simplify use of cpuflags in pkgsrc
# abs@netbsd.org - freely distributable, no warrenties, stick no bills.

# Try to optimise based on CPU
# Does not affect any package that overrides CFLAGS/CXXFLAGS/CCOPTIONS
# Sets five variables:
#
#	CPU_FLAGS	The output of cpuflags
#	CFLAGS		Has CPU_FLAGS appended
#	CXXFLAGS	Has CPU_FLAGS appended
#
#	CPU_DIR		CPU_FLAGS with spaces stripped (eg: for use in PACKAGES)
