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