33# Generate compile-rules for the modules that we are using in libraries or
34# programs.  We are listing them explicitly because we have turned off the
35# suffix rules (to force compilation with the appropriate flags).  We could use
36# make-recursion but that would result in makefiles that are useless for
37# development.
38#
39# Variables:
40#	model directory into which objects are compiled.
41#	MODEL (uppercase version of "model"; toupper is not portable)
42#	echo (yes iff we will show the $(CC) lines)
43#	subset ("none", "base", "base+ext_funcs" or "termlib")
44#	crenames ("yes" or "no", flag to control whether -c & -o options are used)
45#	cxxrenames ("yes" or "no", flag to control whether -c & -o options are used)
46#	traces ("all" or "DEBUG", to control whether tracing is compiled in)
47#	srcdir is expanded when "configure --srcdir" was used
48#
49# Fields in src/modules:
50#	$1 = module name
51#	$2 = progs|lib|c++
52#	$3 = source-directory
53#
54# Fields in src/modules past $3 are dependencies
