#
# Don't call this macro directly, because it contains some occurrences
# of '$1' etc. which will be interpreted by m4. So you should call it
# with $1, $2, and $3 as arguments, which is what AT_DATA_CALC_Y does.
#
# When %defines is not passed, generate a single self-contained file.
# Otherwise, generate three: calc.y with the parser, calc-lex.c with
# the scanner, and calc-main.c with "main()". This is in order to
# stress the use of the generated parser header. To avoid code
# duplication, AT_CALC_LEX and AT_CALC_MAIN contain the body of these
# two later files.
