#  makefile.math			Jul 04
#    (from makefile.nm)

# Assumes jgofs distribution 1.5 or later and that this file,
#    along with the sources, is in src/* under the jgofs root.

# Can be run standalone if:
#	1) jgofs_root/build-env.pl has been executed first in context of
#	   this process (eg,
#		jgofs_root/build-env.pl -sh > /tmp/build-env.sh
#		source /tmp/build-env.sh
#	   )
#	2) jgofs.a library has already been built


#  15 May 09.  Remove USE_DOUBLE.  WJS
#  21 Jul 05.  WJS
#	Remove the -NOTOPLINKS spec.  Obsolete after we added capability
#	  for per-button control (normally done by env vars in object
#	  defns)
#  17 Jul 04.  WJS
#	Complete replacement of makefile.math by makefile.nm, mostly to
#	  implement 7 Jul comment (from makefile.nm - other comments from
#	  original makefile.math)
#   7 Jul 04.  WJS
#	Mods to take advantage of new build stuff (add ${CONFIG_FILE}, etc
#	  dependencies; build optdefgb, etc).  CONFIG_FILE (eg, build-env)
#	  is used to force builds in addition to its natural dependency role
#	Mod to use outer_make_macros.include
#  11 Jan 99.  WJS
#	Changes for outer_brev (including USE_DOUBLE switch)
#  21 Nov 98.  WJS
#	Change method name back to math so it won't conflict w/Chris' real
#	makefile for optmath.
#  17 Nov 98.  WJS
#	Typo fix to CLH mod.  Mods to comments
#	Took out clean option
#     Nov 98.  CLH (comment by WJS)
#	Add directory for #include files.
#	Don't try to make methods directory if it already exists
#	Add clean option
#   7 May 98.  WJS
#	Correct typo in I_LIST.  Correct comment.
#  21 Apr 98.  WJS
#	Define OO_OUTER in case outer_brev is being used
#  15 Apr 98.  WJS
#	Switch method name to optmath
#   3 Apr 98.  WJS
#	makefile.math (comments below from make_method.jgofs15)
#   3 Apr 98.  WJS
#	Use I_LIST instead of individual -Is
#	Fix typo which omitted METHOD_CFLAGS from non-BUTTONIMAGESDIR case
#   2 Oct 97.  WJS
#	Fix typo in -I switch.  Add -I to look in INCDIR
