Simplified makefile definitions and rules.

# Every time we clone a new tree, i.e. every time you need to change 
# the RELEASE macro, you will need to consider each of the macro's in this
# group. RELEASE_NUM must be < 214 and preserves the monotonicity of the 
# inst version numbers. See man page for mkversionnum for more details.
# RELEASE_NAME is the human readable product name string for hardware
# specific releases.  it must be empty (no spaces or anything) for the
# base release.  It should match reasonably well the label printed on the CD
RELEASE=2.2
RELEASE_MAJOR=2
RELEASE_MINOR=2

#
# Default STYLE for binaries - this sets what the base level (i.e. no
# explicit makefile flags) binaries will be made up of. This defines
# both the ABI and ISA defaults.
#
# Note that 'make'-files (as opposed to 'smake'-files) will use
#	DEF_CSTYLE and DEF_GLDOPTS - and OBJECT_STYLE will be set to
#	DEF_OBJECT_STYLE - thus ALL 3 must agree for both make/smake-files
#	to produce the same results.
# The 'DEF_GLDOPTS/DEF_CSTYLE' is for makefiles that have no specific
#	ABI/ISA requirements
#
# If DEF_CSTYLE should change then LIB_LOCATION and ROOTRLDNAME should also
# reflect the change to the DEF_CSTYLE.

# LIB_LOCATION is for Makefile's who have hardcoded pathnames
# to a lib.  For example, 
#       LLDLIBS=$(ROOT)/usr/lib/libw.a
#       should be changed to ...
#       LLDLIBS=$(ROOT)/usr/$(LIB_LOCATION)/libw.a

# This way when the default object style changes we only
# need to change it here.

#	change ALL makefiles that don't explicitly set OBJECT_STYLE

# compile both 32 and 64 bit versions but just want 1 of each and to
# pick up the current favorite.

# would permit it to be easily changed to compile N32.
